thats not all his selective memory is forgetting
what about that pair down in Jacksonville, Henderson 9th overall (2002) & Stroud 13th (2001)???? or New England Richard Seymore 6th pick in 2001 or am I the only one who noticed the development & much improved play of Jets DT Dewayne Robertson taken 4th overall in 2003???? We could both throw numbers on both sides of the equation to stress our points, however if you look at this years draft it should be obvious even to the casual observer there are both LB's & DE's that convert to the NFL as OLB's, here are just a few-
Derrick Johnson LB, David Pollack DE, Thomas Davis S, Dan Cody DE, Matt Roth DE, Barrett Ruud, Kevin Burnett LB & Justin Tuck all 1st round possibilites. Compare those numbers to the quality DT's available,
Anttaj Hawthorne & Shaun Cody.
hence your opinion that its much harder to find OLB's in a 3-4 is
