i dont really think you can blame tomlin. he was hired for one reason and was expected to do just a couple things: organize practices, stay out of the way and let the coordinators manage the game, and say the right things to the media. he has done that. the owner is getting exactly what he wanted.
AH, I think he is expected to do a little more than that, like offer leadership and keep discipline and attitudes in line. He kind of failed on that front last year: dumb penalties, dumb turn overs, lack of focus, lack of effort, etc.
