There's like 4 or 5 guys who have been doing a better job than him. He's not going to put up the numbers that a QB from an offensively focused dome team will be able to but he's much better than mediocre. You aren't paying attention if you think he's mediocre. You're not paying attention to the NFL if you don't think his decision making and throwing accuracy leave A LOT to be desired. I think there's plenty of room for improvement, no doubt. But every QB makes bad decisions/throws, and most of them are much worse than Cutler. 23rd in completion percentage, 21st in yards per attempt, tied for 16th in TD's, tied for 7th most in INT. 24th in QB rating, 30th in Dyar, 30th in DVOA, 19th in QBR. His offense around him is below average but not horrible, and some of those metrics account for that anyway. I don't see any evidence to support him as a top 5-6 QB.
