People hate to think about context.
Sheard was drafted to play in the 4-3 under Dick Jauron. In two years under the 4-3, he had 15.5 sacks.
His rookie year he played RDE and had his best year. After his first year they moved him back to his college position of LDE, where he still had a really good year.
The head coach got fired, a new coach came in, fired the defensive coordinator who just had a top 5 defense a couple years before, and now he was asked to learn a new position and probably drop into coverage more. At first he was in the same position as DeMarcus Ware which is the primary pass rushing outside linebacker, but the second year he was put in that Anthony Spencer role on the left. And obviously his numbers fell off.
Sheard would be a great player to bring in for that LDE position and the best part is we could probably still sign another player to play RDE.
Imagine
LDE - Sheard, Mincey
LDT - Paea/Fairley, Hayden/Brent
RDT - Crawford, Melton/Okoye
RDE - Hardy, Lawrence
I think that would be pretty impressive.
