Chattanooga is a team who plays drastically better at home. On the road this year they have been a great go against because their inflated record has made them either favorites or just small dogs.
If you count up all their home conference games since 2009 (including the 3 games in the SoCon tourney in 2009 which they hosted) they are 20-7 at home in conference play.
I do not by any means think Chattanooga is a super team, far from it, but they play extremely well at home. They even took down College Of Charleston, who is the class of the conference this season IMO.
While the line does seem a bit fishy, it's hard to go against a team who plays noticeably better at home and only laying a point.
As far as injuries, I didn't see anything significant.
