What is all this stuff about Glover played the 3-4 and was a monster? I heard the Parcells press conference, but all that was said was that he played it before.
Who cares? He played it in Oakland, but never made a scratch there. He played a bit of it in NO, but he didn't start making pro-bowls until they moved to a constant 4-3 and he played the 3. Glover has NEVER 'thrived' in the 3-4. He has played in it a bit. That is all.
As far as DE in the 3-4, glover is a true 3-tech DT. His job is mainly a pass rusher, to get up field quickly. In the 3-4, DLinemen have a different role. Their job is to hold their point and eat up blockers. IF they get up field, bonus, but it is a secondary role. They hold up blocks so that the linebackers can roam freely.
Glover is 6'2, 285-295 lbs. His bread and butter is his quickness and ability to get upfield. But he does so against guard singles and such. As a DE, he would go against much larger tackles and often see double teams from the T and G. Further, he doesn't have the mass to hold the point for LBers to roam freely.
Here is an example - Warren Sapp. Warren Sapp, 4 years ago, was the DT that ALL 3-techs were measured against. Glover is about on par with Sapp. Sapp went to Oakland, where he played the 5 tech DE position in the 3-4. He was not good at all.
