This is the week Ryan FitzMagic finally morphs back into Ryan FitzTragic. Because if there's one thing that can finally put an end to FitzMagic, it's an unstoppable monster in the form of Khalil Mack.

To this point, Harvard man, NFL journeyman, and Buccaneers quarterback Ryan Fitzpatrick has been nearly unstoppable filling in for Jameis Winston, whose three-game suspension for allegedly groping a woman ended this week. Fitzpatrick didn't just lead the Buccaneers to a 2-1 record with wins over the Saints and Eagles before dropping a tight contest to the Steelers -- those are three playoff teams, by the way. He also threw for 1,230 yards and 11 touchdowns along the way, becoming the first quarterback in NFL history to the throw for at least 400 yards in three straight games. 

Some day, somewhere, we'll be telling our grandkids and/or pets about this FitzMagical run. We'll also tell them about the day it ended. And the day is coming soon. On Sunday, the Buccaneers face the Bears in Chicago where Mack and the reborn Monsters of the Midway wait. That's when and where FitzMagic will expire. 

I know this is the second straight week I'm beginning my weekly best bets column with a Bears' defense specific introduction, but bear with me here. Because what Mack is doing right now is worthy of recognition. He's transformed a solid defense into a great defense. Through three games -- and keep in mind he missed all of training camp and the preseason -- he's already registered four sacks, 11 solo tackles, three forced fumbles, one fumble recovery, one interception, and one touchdown. 

As a result, the Bears' defense is the league's best by DVOA. They're allowing the fifth-fewest yards (289 per game) and the eighth-fewest points (18.3 per game). They've generated the second-most takeaways with eight and they lead the league in sacks with 14. Mack doesn't have all 14 of those sacks, but his presence alone (he's getting triple teamed at times) and quarterbacks running away from him have directly led to several other quarterback takedowns. For perspective, consider that while the Bears have 14 sacks, the Raiders' defense has 15 total quarterback pressures, as NFL Network's Andrew Siciliano noted.

So which teams should you back in Week 4 of the NFL season? And which team with postseason aspirations gets absolutely stunned on the road by an underdog? Visit SportsLine now to see which teams are winning more than 50 percent of simulations, all from the model that has outperformed 98 percent of experts tracked by NFLPickWatch.com the past two seasons.

As the Bears sit at 2-1 (their first winning record since Week 3 of the 2014 season) and atop the NFC North (their first division lead since Week 16 of the 2013 season), Mack deserves to be in the MVP conversation. The Bears are only 2-1 because of their defense. And the Bears' defense is only good enough to win two games on their own because they have Mack, the best edge rusher in football who makes everyone around him better. The secondary isn't forced to cover nearly as long. Akiem Hicks, a very good defensive end, is suddenly the second priority for opposing offensive lines. Leonard Floyd is the third priority. According to ESPN's Bill Barnwell, "the Bears are third in the NFL in win probability added by their defense so far this year."

On "Good Morning Football" this week, Kay Adams reminded us that it's not just Mack out there destroying opposing offenses. Mack's the centerpiece, but he's been this dominant in the past and that didn't turn the Raiders into a destructive force. This entire Bears defense is worthy of recognition, which is why Mack said recently that he's "thrilled as a mother------" to have joined this team.

And so, with the first of my five best bets, I'm taking the Bears to beat the Buccaneers by more than three points. They're going to end the FitzMagic ride. Fitzpatrick likes to chuck the ball around and give his receivers a chance to come down with wild passes downfield (see: his three picks vs. Pittsburgh). The Bears, with their five picks in three games, like to catch wild passes. 

For what it's worth, the Buccaneers haven't announced who will start Sunday's game. But I'm operating under the belief that it'll be Fitzpatrick considering how well he played in the first two games and how he rebounded from a dismal first half on Monday night with an explosive second half. The Buccaneers get a bye week after Week 4, which seems like the perfect opportunity to put Winston back into the starting lineup. And if the Buccaneers do make the move to Winston before Sunday's game, they're still going to have issues with this Bears defense. While Winston's been a substantially better quarterback than Fitzpatrick during their careers, he can also be maddeningly inconsistent and turnover prone like Fitzpatrick. I'm not sure it really matters who's at quarterback for the Buccaneers in this game.

Let's get to my five best bets.

All odds via SportsLine

Last week: 3-2
This year: 11-4

Bears (-3) vs. Buccaneers 

The biggest concern I have about this game is the Bears' offense -- specifically, second-year quarterback Mitchell Trubisky. But I still believe in his upside and I believe in Matt Nagy's system. He's creating openings, but Trubisky isn't seeing them or hitting them with accuracy. 

At some point, it's all going to click. Against a defense that is 29th in DVOA, 31st in yards allowed, and 29th in points allowed is a good time for that to happen.

Chiefs (-5) at Broncos

When will Patrick Mahomes' wild run end? After Mahomes' blistering start -- 896 yards and 13 touchdowns in three wins -- that seems to be the question on everyone's mind. 

Except, I'm not sure if it'll ever end. That's not to say Mahomes is going to throw for 4,800 yards and 69 touchdowns. He's going to slow down at some point. But if you're waiting for Mahomes to suddenly turn into an ordinary quarterback, you're going to be waiting forever. This Chiefs offense is anything but ordinary. They're a video-game cheat code.

It's part Mahomes.

It's part Andy Reid.

It's part weapons.

The Broncos might slow them down more than the 49ers, Steelers, and Chargers did, but they're not going to completely shut them down. Through three weeks, the Broncos defense is ranked 14th in yards, 16th in points, and 16th in DVOA. This isn't the 2015 Broncos defense anymore. And their quarterback problem has hardly been fixed by the arrival of Case Keenum, who's thrown two more interceptions than touchdowns so far this season.

The Broncos won't be able to stop the Chiefs and they're not going to be able to keep up. 

Seahawks (-3) at Cardinals 

The Cardinals just aren't any good right now. They've scored 20 points all season long. With Josh Rosen and David Johnson, their future is bright, but Rosen's development is only just beginning. After getting thrown into just about the worst possible situation a week ago -- down late in the fourth quarter against that Bears defense -- Rosen will make his first-ever NFL start against the Seahawks. 

The Seahawks might not be any good either, but I don't think they're as bad as they've been made out to be. They've lost two tight road contests and hammered the Cowboys at home. Earl Thomas is playing out of his dang mind (extend him already), having notched three picks. Don't be surprised if he gets another against a rookie making his first start.

The Seahawks might not be a good team, but they're good enough to take advantage of the Cardinals' all-around inadequacy and an inexperienced Rosen. Oh and hey, Doug Baldwin might make his return.

Packers (-10) vs. Bills

The Bills' surprise beatdown of the Vikings after traveling to the wrong state on Saturday (not really) has done nothing to change my mind about them. Assuming the Bills show up to the right state on Sunday, they're probably not going to get the gift they got on Sunday, when Kirk Cousins fumbled twice deep inside his own territory. The Bills raced out to a 17-0 lead in the first quarter and two of their scoring drives netted six plays and 29 yards. Give the Bills credit for beating the Vikings. Nobody saw it coming. But that doesn't mean they'll do it again.

Aaron Rodgers isn't Kirk Cousins. He doesn't turn the ball over (1.6 career interception rate). He might be hobbled, but he's not going to give the Bills free points. Even though the Packers are down a couple defenders, I'm skeptical the Bills will be able to move the ball against the Packers consistently enough to keep pace with Rodgers. The Bills burned me last week, but I'm willing to go against them one more time.

Bengals (+5) at Falcons 

The Bengals might be good and the Falcons are banged up more than any other team, having lost Keanu Neal, Deion Jones, Ricardo Allen, Andy Levitre, and Devonta Freeman to injury. Four of those five players won't play on Sunday (Freeman's status is up in the air). The Bengals, at 2-1, have been scoring at will -- nearly 30 points per game -- and their defensive line can cause problems for the Falcons. It's worth noting that A.J. Green, who hurt his hip last week, appears to be fine. 

I don't really know who wins this game, but it feels like a game that'll be decided by a field goal.
