This is coming from the same guy that argued the Jets valued Quincy Carter and that Quincy did not have a drug problem!!
Now, Belli also must only be as successful as Weis and Crennel because thus far he has not shown the ability to win a champoinship without them.
The logic can be applied both ways, if you do your homework you will learn that Bill Parcells was the defensive coordinator of the Giants and was excellent thus considered for the head coaching position.
He moved them to the 3-4 and and positioned LT to be the freak. Any good head coach is considered as much by aquiring and positioning good coaches. The credit goes to the head coach because he selects them and plays positionally to their respective strenths for the team. Parcells kept Belli, Crennel and personally added Weis to his credit.
Belli failed miserably in CLEV and it is no fluke he went after all of Bill Parcells staff when he went to NE. Parcells drafted the core players that Belli was able to use as leaders for his champoinship run. Belli is a solid coach, but certainly he learned from Parcells even if there was stylistic differences. To me this is an ego issue as most can clearly see to be the case.
Bill Parcells is building a championship team again here in Dallas so stop being a hater and get on board because your perspective is simplistic and can be argued otherwise when the same logic is applied to Belli as well. There is more than just sound coaching that goes into the equation, Bill could have easily won the 2 Bowls without Belli and hopefully will win one here in Dallas as such.
