I think a good analogy would be Denver and Elway. Elway a generational talent at QB, went to multiple superbowls with Reeves. They made a change after the losses. However it took Shanahan to get them to the promised land. Reeves was a good coach, got Atlanta to the SB, Im sure he was also a nice guy, just not a SB winning coach. Sean hasn't even made the conference game, let alone gone to multiple superbowls.
