Question about Colts Titans game

[bosbabiesarm]

Both teams have records of nine wins and seven losses the Titans are at home and hold six wins versus one loss record at home Why are the Colts the favorite, they are three and three their last six against the spread. The Titans are two and four the last six against the spread. Why is Indy the favorite?:shrug:xstop

think indy is probably the better team and luck is playing well guessing the oddsmakers figure take the the team with the better qb in what shapes up to be a close game if you watched tenn last week they struggled to beat wash and while tenn def. is good their pass d can be exposed just think indy better all around team BUT it is the nfl and tenn at home is tough so not trying to talk you into indy just trying to explain why indy is favored but what do i know will be looking for you plays this week
