I am saying you, being an Eagles fan, kind of crapped on Quinn and used his sack total the last five years to make a claim he really isn't that good and yet when you use the same criteria for an Eagles DE, Graham and Quinn are fairly comparable.
That being said, Graham is probably the more rounded player but I don't think the gap is as big as you want to think.
Because they’re not the same type of player. I’d never use 50+ yard catches to define Witten’s career. Quinn isn’t as good of a run stopper as Graham, he can’t play DT like Graham, and he doesn’t get non-sack pressure like graham. For most of his career his contracts have been justified by ballooning sack totals, which have declined as he’s gotten older. So it’s fair to say that’s why Quinn isn’t too 200.
I could reference NFLN, PFF, ESPN, the people who paid Quinn vs the people who paid Graham, or even the pittance you gave up to acquire Quinn. He’s a starting caliber, veteran DE. The accolades stop about there.
