If the Colts were healthy they would have won. They are very much injured, Harrison isn't even playing, that's like Dallas losing Owens or the Panthers losing Smith. Bottom line is, when they're healthy, they're arguably the best team in the league, but they have way too many injuries right now.
Chargers suck! Colts had no business being in that game, down 23-0, and that "simulated snap" penalty was BS, they just shifted, the ball wasn't snapped, Manning's hand wasn't even under center, the hell?
