There is a huge misconception about Jim Bates.
You are right that players and fans loved him, but I think it was due more to the relief of not having Wannstache as coach anymore.
Jime Bates is as vanilla as they come. He would let the players play in his vanilla schemes. Fortunatley at the time we had about 12 Pro-Bopwlers on defense alone, which made him look like a genious.
But the fact that he was not a good coach came out when he was not offered the Dolphins coaching position.
He then went on to Green Bay, where he could not make the defense better, only to bounce over to Denver, where he had better players play in his vanilla scheme, however, once the Broncos started losing players on defense, they ultimatley gave him the boot.
So you see, Jim Bates is as vanilla as they come. He let's his players play, but unless you are full of talent on defense, you are not going to get very far.
