The Super Bowl is the one NFL game where public money outweighs sharp money. The public almost always bets Over especially on marquee matchups such as this one. The oddsmaker knows that. So I see value on the Under. 
Much is being made of the Buccaneers being the home team because the game is being played at Raymond James Stadium in Tampa. But as far as the total is concerned that venue is a plus for the Under. It's an outdoor stadium with a grass field. So it's not a fast surface. The two teams met there this past Nov. 29 and the Chiefs won, 27-24, for a combined final score of 51 points. 
Patrick Mahomes is the most feared QB in football. Tyreek Hill is the most dangerous wideout. Travis Kelce the best tight end. I acknowledge all of that. But it's difficult to produce big points against a very good defense without a decent running attack. I don't see the Chiefs being able to run on Tampa Bay. No team could during the season. The Buccaneers had the No. 1 rush defense in the NFL. The return of star nose tackle Vita Vea has only strengthened that unit. Clyde Edwards-Helaire hasn't looked good after being out with hip and ankle injuries. Le'Veon Bell doesn't have much left and he missed the AFC title game due to a sore knee. 
This puts nearly the entire onus on Mahomes. He's being asked to put up four-to-five touchdowns - as you need TD's not field goals to get above this high of a total - with a lackluster ground attack, facing a strong defense and without his starting offensive tackles. Right tackle Mitchell Schwartz was put on injured reserve in Week 11 and left tackle Eric Fisher suffered a season-ending Achilles tendon injury in the AFC title game. 
Mahomes was brilliant in the title game victory versus Buffalo. However, he was merely a mortal in his previous five games with an 8-to-5 touchdown-to-turnover ratio. Mahomes hasn't faced an insider linebacker duo the caliber of Lavonte David and Devin White. These guys can not only effectively blitz, but also cover well. The Buccaneers also have two tremendous edge pass rushers, Shaquill Barrett and Jason Pierre-Paul. Those two have combined for 45 1/2 sacks during the past two seasons. The Buccaneers have a solid secondary, too. Safety Antoine Winfield Jr. showed star ability in his rookie season. Cornerback Carlton Davis shut down Michael Thomas and held Davonte Adams to 67 receiving yards during Tampa Bay's last two games. 
Todd Bowles is an elite defensive coordinator. He gave Aaron Rodgers more trouble than any other defensive coordinator this season. Bowles is aggressive, but also shrewd. The Buccaneers can pick their spots blitzing - which is dangerous against Mahomes - because Barrett and Pierre-Paul are such good pass rushers and the Chiefs are minus their two best offensive tackles. 
I envision the Buccaneers being conservative on offense using more running plays than expected. Both Leonard Fournette and Ronald Jones are healthy. They are good players for Under bettors because they are inside runners who are more reliable than flashy. 
The Chiefs have a bend-but-don't-break defense. Many of their defensive statistics were below average. But they are above average in the category that matters most - points allowed. Only nine teams gave up fewer points per game than Kansas City, which allowed 22.6. 
Chris Jones and Frank Clark give the Chiefs two good pass rushers. Safety play is huge versus Tom Brady. Kansas City is covered there, too. The Chiefs are deep at safety. Tyrann Mathieu and Juan Thornhill are both excellent. Mathieu has the most interceptions of any safety during the past two years. 
Here are some prop bet recommendations. Obviously best to shop because numbers and prices vary. Most of these props are courtesy of the Westgate sports book. 
Under 10 1/2 Accepted Penalties 
Accepted offensive penalties were the lowest in the NFL since the modern 32-team era. There seems to be an unwritten mandate from the league to officials to cut back on penalties. 
Few penalties are likely going to be called in the Super Bowl. The league doesn't want their showcase game to be littered with yellow flags.
There were just six penalties accessed in the NFC title game. Tampa Bay had only two. There were seven penalties marked off in the AFC championship game with Kansas City accounting for just three.
During the 12 postseason games, there were 10 or fewer penalties in nine of the games. That's 75 percent. 
The Buccaneers had 12 penalties in their three playoffs games for an average of four. The Buccaneers were tied for 20th in penalties during the regular season. 
The Chiefs had the fourth-most penalties during the regular season. That's a big reason why this penalty total prop is at double-digits. However, the Chiefs had just three penalties marked against them in their AFC title win against Buffalo. 
You could see in the title games that official's were only calling obvious fouls. They were letting a lot of physical defensive play, such as holding and grabbing, go especially in the Buccaneers-Packers game. I don't see why that would change for the biggest game of them all. 
Cameron Brate Under 26 1/2 receiving yards
Brate is a short-yardage, red zone target. I don't see Tom Brady looking for Brate outside the red zone when he has Mike Evans, Antonio Brown, Chris Godwin, Scotty Miller, Tyler Johnson, Leonard Fournette out of the backfield and fellow tight end Rob Gronkowski to throw to. This doesn't leave room for Brate.  
Tyrann Mathieu Over 4 1/2 assisted/solo tackles
Mathieu is one of the most productive safeties and he figures to be plenty busy. He's a defensive centerpiece, similar in chess terms to a queen. I wouldn't be surprised if he had more than four solo tackles. When you add assists, it's a no-brainer for me. 
Ronald Jones Over 34 1/2 rushing yards
I believe the Buccaneers are going to run more than some expect in order to keep Mahomes and the Chiefs offense off the field for as long as possible. Leonard Fournette has the higher rushing Over/Under yardage figure, but Jones is Tampa Bay's best running back in my view. Jones had a breakthrough season rushing for 978 yards. He averaged 5.1 yards per carry, which was the eighth-highest in the league. Fournette is going to get carries, but so is Jones. 
Most Valuable Player
I'd make a pizza wager on linebacker Devin White at 40-1. 
I like the Under so a lower-scoring game than expected and a Tampa Bay victory could put White in contention. I do a Rotisserie-style fantasy football league in which tackles and sacks are separate categories. So I can tell you White is just a tremendous talent since I've watched him closely. He piles up tackles and gets sacks, too. There is recent precedent for defensive players winning Super Bowl MVP honors. It's happened twice in the last seven seasons with Malcolm Smith doing it and Von Miller achieving the feat five seasons ago.
