The bigger issue with Tannenbaum is how his decisions impact the ability to assess everyone else.
Is Grier a puppet? How many decisions have truly been his? Would he have drafted/signed differently?
How bad is Gase? Needing to cut players mid-year in consecutive years to change the culture. Are these truly his picks? Would he have built the team differently? Is he compensating in his coaching for have crap players and is making him look bad?
Listen, a coach can call a masterful game. But if the players don't execute, how would you know?
Does he really have control of his team or is there some leveraged relationships he must swallow because of overpaid contacts or other player/FO relationships?
I think the most disgusting thing in all of this is how documented MT's past and tendencies were, yet we hired him anyway. He is who we KNEW he was.
And, like all businesses, the first and last word lies at Ross' feet. It's on you Ross.
