Let me be clear. His track record doesn't make him one of the best coaches of our generation. I'm going by what I saw him accomplish with no quarterback, what I know of him as a person, and what I feel he could have done with a legitimate NFL QB, much less a great one in Flacco. I'm not saying that his 9 years make him one of the best coaches of our generation.
Ok fair enough, he did more with less, he overachieved -- I can agree with you there. It's very hard to make it in this league without a legit QB, no disagreement. I don't think that makes him one of the best coaches of our generation and results matter here. Only making it past the divisional round once matters.
