Really? What data did he have for firing Art Shell...twice?

The first time was because of the Marcus Allen situation. The second time he had no "reason" but he wanted Lane Kiffin there because he felt Kiffin was the "right person"

What data did he have for firing Shanahan?

Shanahan was a young coach with veteran assistants and a poor record (Notice the trend).


What data did he have for blackballing Marcus Allen thru most of the latter part of the 80s into the 90s?

Marcus Allen held out until the last minute for a few years in a row after he won MVP. Allen didn't agree with what he was getting paid (this was before free agency). He consistently held out and Davis told Shell to bench him (which in turn was the beginning of the end of Shell's first reign). Two stubborn egos. Allen and Davis got along real well at first. But the contract issue hurt them both ultimately. Besides, they had Bo Jackson during the time so they didn't HAVE to pay him top dollar.

I take everything that man say with a rock-sized grain of salt.
