You ready for a pretty great weekend or what? College basketball has a nice lineup on Saturday starting at noon, with No. 1-ranked Villanova hosting Providence, and going late into the night, it should give us a lot to discuss come Monday. And on Sunday, there's a couple of important bubble-type games peppered in.

We're here to help you sort out what matters most. There's more than 150 games going down this weekend. Below are the 10-12 you should be tracking, and the storylines therein.

And remember, before the games start, the NCAA is holding a very important summit with some of the sport's most influential rankings-minded figures. Friday's meeting could alter the way the tournament field is selected and seeded, beginning in 2018. That could be the most critical event of the weekend.

What to watch for

1. Arizona's big opportunity

The 4 p.m. ET game on CBS on Saturday is Arizona at UCLA. The Wildcats are 17-2 and have turned into quite a story. Sean Miller's in the running for Coach of the Year -- and so of course is UCLA's Steve Alford. Miller, for the 20th time this season, won't have his best player on the floor. We found out this week that Allonzo Trier has been ineligible to play all season because he unknowingly ingested a performance-enhancing drug last offseason. He cannot play until his bloodstream brings back results that are below the NCAA's mandate.

Despite this, Arizona's had a great year out of freshman Lauri Markkanen, and the Wildcats' only two losses have come on neutral floors to two really good teams by a total of 11 points: Butler and Gonzaga.

UCLA is in control of chasing a 1 seed right now, but its chances will take a big hit if the Wildcats can upset the Bruins in Pauley Pavilion. This is the one you want to make time for beyond all others this weekend.

2. The battle continues for ACC's 1 seed

Louisville and Florida State both are on the path (but have so much to prove) to earning a No. 1 seed at this point, for no other reason than the champion of the ACC will be in discussion to get on the top line. FSU is now 17-2, has seven wins against teams ranked in the top 50 of the RPI, and it's won four of its last five games against ranked teams. Louisville is 16-3, just manhandled Clemson, and is trying to get to 5-2 in the league. FSU, North Carolina (plays at Boston College) and Notre Dame (hosts Syracuse) are all 5-1.

So the ACC should get some interesting movement this weekend, but Louisville-FSU is the headliner.

3. Kentucky's elite offense meets its match?

I doubt it, but the fact of the matter is that South Carolina enters this weekend as the No. 1 team in points-per-possession allowed in college basketball. Kentucky's offense ranks No. 2 in points-per-possession. The game is at Rupp Arena. South Carolina won a home-game rock fight over Florida earlier this week to establish itself as the No. 2 team in the conference. But the gap between Florida and USC as compared to USC and UK feels like a gulf compared to a stream. I don't think South Carolina is in UK's class, and the Wildcats (6 p.m. ET tip on ESPN) will have a chance to show the country why they are, without debate, so much better than the rest of their league. If South Carolina can keep it close, though, then it's going to alter the perception of Frank Martin's team. A close Kentucky win would make people take the Cocks more seriously.

4. Undefeated Watch

Just Gonzaga, of course. If you're interested in some fun college basketball history, you should really check this out. That's a look at how the final unbeaten team in college basketball performed in the NCAA Tournament in every year since 1992. National champions are rare, but tournament success is not. Gonzaga moved to 18-0 with an 88-57 win at Santa Clara on Thursday night. The 19th game comes on Saturday night at 8 p.m. ET, as the Zags will be at home against Portland. It seems automatic. The Bulldogs woke up on Friday as the new No. 1 team in KenPom.com's rankings. They're No. 5 in Sagarin's ratings, No. 8 in LRMC, No. 10 in RPI.

5. Big 12 road tests

West Virginia is at Kansas State (6 p.m. ET, ESPN2), and the Mountaineers are coming off that overtime loss against Oklahoma. For WVU, having any hope of winning the Big 12 will mean winning this game, but Kansas State's better than many realize. Are the Wildcats a top-25 team? No, I don't think so, but they're without question top-35, and are building an NCAA Tournament resume. So this is going to be tough for the 'Eers. The K-State player you need to know about: senior power forward D.J. Johnson.

The other Big 12 team facing an interesting test: Baylor, which plays at TCU on Saturday at 8 p.m. on ESPNU. The Bears are 17-1, still have a claim to the best resume in college basketball, and in my opinion would have, still, the strongest argument if they're able to beat TCU. The Horned Frogs -- one of the most surprising teams in the country -- already have more wins this season than last. I think Baylor wins, and I think this is one of the three best games we'll see among major-conference teams on Saturday.

6. Big-time teams playing without their best players

We'll get to see how Creighton adjusts without Mo Watson, Jr. We know the senior point guard is not returning this season. His college career, unfortunately, is over. The Bluejays, who are off to a school record 18-1 start, host Marquette at 2:30 ET on Saturday on Fox Sports 1.

We'll get to see how Indiana responds without OG Anunoby, who was ruled out for the season on Friday. This is the second straight year Tom Crean's taken on a major injury to a player; last season, James Blackmon, Jr. had a season-ending injury to his knee. Indiana hosts Michigan State at 4 p.m. ET on Saturday on ESPN.

We'll see how Oregon responds without Dillon Brooks. The Ducks' best player left in the first half of Oregon's Thursday night home win over Cal with a weird lower-leg injury. We don't know anything else aside from that at this point. The Ducks host Stanford, a 6 p.m. ET tip on Pac-12 Network. All of these injuries are significant and will essentially derail the Final Four hopes of each team.

Let's get through the weekend -- and the rest of this season -- without another major injury to any top-30 players in the sport, please?

7. What to watch, in addition to football, Sunday

The Sunday slate is light, but Northwestern will try to firm up its NCAA Tournament resume with a win at Ohio State. Far from a gimme. The Wildcats are one of 10 teams highlighted here who can get to the tournament after missing out last year. In fact, Northwestern's missed out on every NCAA tourney ever. NU-OSU is a 1 p.m. ET tip on Big Ten Network.

While the big football is going down, Virginia Tech will play a road game at Clemson, and this is already Clemson's last stand for at-large status. The Tigers are 11-7 with a 1-5 mark in the ACC, losers of five straight. Remember last year, when Clemson got off to a 6-2 start in the ACC and became a late-January storyline in college hoops? Exact opposite this time around. Virginia Tech, meantime, has a lot to prove, and it would be near the front of the line of bubble teams if it doesn't win this game. Beating Duke without Grayson Allen is no meal ticket to March.

Two more Sunday games: VCU and Xavier are both really good programs who are in need of a morale-boosting home win against inferior competition. Xavier welcomes in Georgetown at 2 p.m. ET on CBS. The Rams host La Salle at 2 ET on NBC Sports Network.
