Better team getting points. That's it in a nutshell. The Colts also are getting back their best running back, Marlon Mack, and perhaps their top wide receiver, T.Y. Hilton.
The Buccaneers are error-prone offensively with Jameis Winston remaining a model of inconsistency.The Bucs also rank 30th in scoring defense giving up 28.8 points a game. 
The Colts are much more solid in the trenches, too. 
Indy is 6-2-1 ATS in its last nine road games. Tampa Bay is 2-5-1 ATS the past eight times as a favorite, including 1-3 ATS this season.
