Most will correctly point out that Martz got out schemed by Packers defensive coordinator Dom Capers. He certainly made his share of mistakes.
But in my book neither Martz nor offensive line coach Mike Tice need apologize for anything when it comes to the job of coaching. They both did the best they could with second rate personnel where the game of football is actually played, at the line of scrimmage. The whole season from the bye week on was a damned miracle.
