It kinda depends on how your league scores points. But I think the obvious choice here is Cutler. He's thrown for more yards and more TD's that Garcia. The Colts have a defensive passer rating of 76.6 and the Chargers have a defensive passer rating of 98.3. Cutler should be facing the weaker defense and has been putting up the better numbers (except for his interceptions.)
So, unless your league really, really scores interceptions negatively, then I'd definitely go with Cutler.
