The truth of the matter is that it doesn't matter what Whaley or Rex's roster building philosophy or strategy is. Teams have succeeded with different philosophies and strategies. That's not the issue. Rex was a bad coach who couldn't get his players to play his complicated and outdated system. He was more determined to force his players to adjust to his system rather than adjust his system to the players limitations and strengths.
Rex was an undisciplined person that was reflected in his chaotic coaching. The record in Buffalo and the downward spiral that happened in Buffalo was similar to what happened in NY. The longer he coached, wherever he was, the worse his team performed.
Coaching matters. That was blatantly demonstrated in the two years that the corpulent coach was here. With his departure it is addition by subtraction. I'm very encouraged with the new more silent hire. There is no quick fix for the damage done to this team by the former obtuse HC.
Bold take from a guy who just said
The Rex hire was a Pegula hire. It was widely reported that Doug favored Hue Jackson. Saying that Whaley and Rex had the same idea about building a team is like saying that there was little difference between Trump and Hillary. It is a ludicrous idea. Rex's idea of building a roster is like Calvin Coolidge's view of running the government: very outdated and disastrous.
