Even if he didn't have that sack, he'd still be the giants career sack leader (141.5 with favre sack removed compared to LT 132.5, not to mention Strahan didn't have a hand in the dirt in front of him to take up some OL blocks). If Strahan were a 3-4 LB, he probably would have had even more sacks than he did record...
Rest assured, Strahan will eventually get in. It's just a matter of time or attempts.
He got screwed. I didn't think he'd get in this year, but after seeing those that did, he clearly deserved it. I saw them all play and while good, Strahan deserved the nod over some of the others. I say it's the anti-NY vote and not wanting to put two former Giants, yeah I know Parcells was also a cowgirl, but is best remembered as a Giant.
If I had to guess, they didn't want two Giants getting in at the same time (Parcells) or both DEs of the same generation getting in at the same time (Sapp).
