I don't get it... Why do people think Zimmer would coach the aggressiveness out of any guy? Zimmer, before Parcells, was very aggressive. He used to blitz alot to try and account for the weaknesses in coverage before Bill came... Remember that I am not arguing that he was successful before Parcells.. Zimmer couldn't generate a pass rush than.. but he could not be accused of being non-aggressive...
The lack of aggressiveness if anything is because of Bill Parcells.. He plays a lot of zone... I remember a quote that was referenced in a Dallas game where the announcer stated that Bill Parcells was saying that everybody wants to make Ware a sack specialist, while he wants to make him a linebacker.
Bill Parcells has a scheme that focuses on particular things... If anybody is going to make somebody not aggressive, it is going to be Bill Parcells... Unless of course you snort cocaine, like LT... than anybody, including Parcells, would have problems taming you...
Parcells prefers to keep games close, because he believes it gives the team a better chance to win... he is very fearful of the big play... that is why he plays a very conservative style....
