2018 NFL Draft: Mark Andrews' big game catapults the tight end into our Top 20

When analyzing Oklahoma's 56-7 thrashing of UTEP, Baker Mayfield's 329-yard outing is the presumed headline, but Mark Andrews was the most impressive Sooners offensive player on Saturday.

The 6-foot-5, 250-pound tight end had seven receptions for 134 yards -- 19.1 yards per catch -- with one touchdown. But his stats alone weren't the only story; it was how he accumulated those statistics that was vital. Andrews was a yard-after-the-catch monster, rarely going to the turf immediately after catching a pass. He executed ridiculous jump cuts and back jukes to find open field then turned on the jets to rack up extra yards.

Andrews had gains of 20, 23, 26, and 45 yards against UTEP. He was Gronkowskian.

Each week during the college football season, there'll be an updated Top 20 prospect list. Here's the first installment.

1. Mason Rudolph, QB, Oklahoma State

Rudolph went into the season as the No. 2 overall prospect and had an efficient albeit unchallenged performance against Tulsa at home. He isn't dinged for the low level of competition he faced because he did make a trio of perfect throws down the field for scores. Rudolph was composed and accurate all evening. The September 16 game at Pittsburgh will be his first tough test.

2. Tyquan Lewis, DE, Ohio State

Lewis was the Big 10's Defensive Player of the Year in 2016, and began his 2017 campaign with a two-sack, two tackle-for-loss performance against a conference foe on the road. He's on his way to an enormous season, and it helps playing alongside Sam Hubbard, Dre'Mont Jones, and the ultra-talented Nick Bosa, who isn't draft eligible until 2019. Lewis isn't flashy, but he bends the edge quickly and packs NFL-like power in his 6-foot-4, 265-pound frame.

3. Harold Landry, DE, Boston College

Landry didn't register a sack against Northern Illinois. That doesn't mean he had a poor game, as he did create quarterback pressure throughout the evening. Per Pro Football Focus, Landry hurried the Huskies signal-caller four times and registered two quarterback hits on just 29 pass-rush attempts. He had six total tackles and a pass deflection too. The chiseled Landry has length to go with plenty of juice around the corner.

4. James Washington, WR, Oklahoma State

Washington was his usual self against Tulsa. He stretched the field on more than one occasion, made some catches outside his frame, and reached the end zone. On the night, Washington had six grabs for 145 yards and two touchdowns. In fact, in his last 21 games, Washington has scored 21 times. He's not an enormous power forward-type of wideout, and that's just fine because he's well-built, tracks the ball extraordinarily well and has serious downfield speed.

5. Sam Darnold, QB, USC

Darnold was just "ehhh" against Western Michigan at home. Maybe we kinda-sorta over-hyped a then-19-year-old quarterback with only 10 career starts? Really though, Darnold has immense potential and did show last year he's capable of playing well beyond his years. And when you think about it, this "average" performance came on an afternoon in which he completed 23 of 33 passes for 289 yards. Darnold's release could get a little more compact, and he'll want to clean up the errors he made on his interceptions against the Broncos for this week's showdown with Stanford.

6. Saquon Barkley, RB, Penn State

It took a while for Barkley to get involved against Akron. Once he did, the fireworks never stopped. He had a relatively easy 80-yard touchdown scamper -- are those ever really easy? -- and amassed 92 yards on his other 13 carries. Barkley also dazzled as a receiver. He had three receptions for 54 yards with an abundance of yards after the catch. It was the ideal Heisman-campaign outing to begin the season for the super-charged runner.

7. Cameron Smith, LB, USC

Due to a targeting penalty in the Rose Bowl, Smith was held out of the first half against Western Michigan, and boy was he sorely missed. The Broncos' offensive line absolutely manhandled the Trojans' defensive front seven in the run game. I never would have guessed I'd write that sentence. When Smith returned in the third quarter, everything changed on that side of the ball for USC. He was a step ahead of pulling linemen, shed them with ease, and finished with six tackles -- four solo -- with two tackles for loss.

8. Lamar Jackson, QB, Louisville

As profiled in QB Stock Watch, Jackson was considerably more comfortable and effective as a pocket passer -- and even when he scrambled -- against Purdue than what he displayed for the vast majority of 2016. Of course he was outrageous as a runner, but we've come to expect that from the reigning Heisman winner.

9. Derrius Guice, RB, LSU

Like with Jackson, we're accustomed to almost unfair runs from Guice on a regular basis. He didn't have any of those against BYU but did end the night with 122 yards and two scores on 27 carries. It seemed as though LSU didn't need to provide Guice with that much of a workload against a clearly overmatched Cougars team that never made it past the 50-yard line. However, he can handle a 25-plus carry game every once in a while thanks to his impressively muscular frame.

10. Derwin James, S, Florida State

Against the reloaded Alabama Crimson Tide, James looked like the player we saw in 2015, the freshman who had 91 tackles, 4.5 sacks, and 9.5 tackles for loss in 12 games. No, he didn't make any enormous splash plays but was the primary spy on Alabama quarterback Jalen Hurts, who finished with just 55 yards on 15 carries. James was everywhere for the Seminoles. I think I'll be writing that frequently this season.

11. Calvin Ridley, WR, Alabama

Ridley put a show against Florida State. He flashed his fluid body-control, intricate route-running, and blazing long speed en route to a seven-catch, 82-yard, one-score effort. Ridley did capitalize on a freshman cornerback taking him on one-on-one for his big-play touchdown but was also a reliable target for Hurts at the intermediate levels against a loaded Seminoles secondary.

12. Mike McGlinchey, OT, Notre Dame

McGlinchey is lauded for his pass-protection ability, and that's what'll make him his money in the NFL, yet scouts will be happy to see such a powerful run-game afternoon for the senior left tackle. Notre Dame rumbled to 422 yards on the ground at 9.2 yards per pop, and McGlinchey helped to open many holes for the Fighting Irish's three 100-yard runners.

13. Mark Andrews, TE, Oklahoma

Andrews looked like first-tight-end-off-the-board material over the weekend. Sure, it was against UTEP, but most tight ends his size don't have the lateral agility and acceleration he demonstrated.

14. Denzel Ward, CB, Ohio State

Indiana's frontcourt of wide receivers out-muscled Ohio State's defensive backs at the beginning of the game, but the Buckeyes secondary, led by Ward, turned the tables in the second half. The 5-foot-10 corner had a remarkable five pass breakups against the Hoosiers and came down with an interception. Though smaller, he has the requisite athleticism to stick with any type of receiver sent out his way.

15. Chukwuma Okorafor, OT, Western Michigan

Okorafor was featured in the Underrated Prospects list that was released right before the season. Despite offers from powers in the Big 10 and SEC as well as Oklahoma and N.C. State, the Michigan native decided to stay home and go to a school for which he could play immediately. Okorafor looked like a varsity senior toying with junior varsity freshmen ... against USC. Quite the accomplishment. After allowing a hurry to future NFL defender Porter Gustin on the opening drive, Okorafor was downright dominant. At 6-foot-5 and nearly 300 pounds with balance and sledgehammers for arms, this left tackle is the player to watch in the MAC this season.

16. Ronald Jones II, RB, USC

Cameron Smith injected life into the USC defense in the second half against Western Michigan. Jones was electric all afternoon for the Trojans. Those two stopped a major upset from taking place. Sure, Barkley and Guice are the top two featured backs in college football, distinctions they deserve. But no running back in the country shifts into fifth gear faster than Jones, and he possesses elite elusiveness and vision as he reaches the second level. He had 158 yards rushing at 8.8 yards per carry with three touchdowns.

17. Josey Jewell, LB, Iowa

Jewell was a gem -- sorry, had to -- in the Hawkeyes' dismantling of Josh Allen and the Wyoming offense on Saturday. The senior had 14 tackles, 2.5 tackles for loss, and two sacks. Jewell was an omnipresent defender. He entered the 2017 season coming off back-to-back 120-plus tackle years in Iowa City, and at 6-foot-2 and 236 pounds, he fits the mold of today's sideline-to-sideline NFL linebacker.

18. Maurice Hurst, DT, Michigan

Hurst boasted his rapid get-off against the Gators but also displayed his football intelligence and play-recognition ability. He had five tackles and one tackle for loss in Michigan's win. Sure, Florida was undermanned due to a variety of suspensions, but Hurst led a triumphant performance by the Wolverines defensive front. The Gators accumulated just 192 total yards.

19. Derrick Nnadi, DT, Florida State

The Seminoles were worn down Alabama late in the game, but individually, Nnadi pushed back Crimson Tide offensive linemen when he wasn't quickly dispatching them to either make tackles near the line of scrimmage or clog running lanes. Not many interior defensive linemen as big as the 6-foot-1, 310-pound Nnadi move laterally as effortlessly as he does.

20. Shaun Dion Hamilton, LB, Alabama

Returning from a knee injury that occurred in last season's SEC Championship game, Hamilton was explosive to the football and delivered a solid pop when he arrived against Florida State. The off-ball linebacker had eight tackles, 3.5 tackles for loss, and a sack in a loud statement game for Alabama. With a mammoth group of defensive linemen in front of him, Hamilton should be in a for productive 2017 campaign.
