"He was strict, organized and competent. Bell hated him.
I don't mean hate as a euphemism here. We're talking VooDoo dolls here. On the other hand, Mazur wasn't too keen on Bell either.
It's difficult to tell where the origin of this hate fest was. Mazur was head strong, had a believe of how he wanted things done and also had a strict military background. Bell accidentally released six players when he forgot what day the deadline for resigning veteran players was. Bottom line, it was everything. These two couldn't agree on where to get coffee in the morning.
Then as time went on, the two would do things for the singular purpose of aggrevating the hell out of the other. For example, in 1971, running back Carl Garrett was one of Mazur's favorite players. On top of that, he was one of the few on the team who weren't bad, old, or bad and old. Bell had to trade him because this was the start of his bizarre campaign to get Mazur fired."
From a couple grains of truth you've got a minefield of misinformation here.
The Pats early days pretty much are pretty much a bizarreo fest without the exaggeration.
