I loved the article except for this:
Which is why you should believe that Belichick forced former New England linebacker Ted Johnson to practice despite not having been cleared from a concussion a few years back. Johnson (who is now suffering from early signs of Alzheimer's in his mid-30s) made the Patriots a better team, which is all that mattered to Belichick.
And why you should believe that Belichick tried to prevent his brilliant defensive coordinator, Eric Mangini, from interviewing for other jobs before he bolted to the Jets. Mangini's career arc meant nothing to Belichick, winning the next game was the only concern.
There is simply no basis for why we "should believe" that part, ESPECIALLY the second part. Belichick didn't "prevent" Mangini from interviewing for other jobs - or the JET job for that matter. He was rumored to have advised STRONGLY against going to the jets, but I never heard anything about him "preventing" anyone from leaving.
In fact, it was Parcells' putting up obstacles to Belichick furthering his career that made it so important to BB that his assisants DID go on to bigger and - well, not BETTER - but bigger things!
