They really did a pathetic job of putting that list together. Notable omissions:
Al "Bubba" Baker (23 sacks -- unofficial stat at the time)
Everson Walls (11 interceptions)
Leslie O'Neal (12.5 sacks)
Simeon Rice (12.5 sacks)
Anquan Boldin (101 rec for 1377 yds)
Dale Carter (7 INTs, I TD)
Dan Marino
Why does Shockey's 74/894/2 get in over Keith Jackson's 81/869/6?
And how does Tony Dorsett's 1007 yards and 4.9 ypc and Billy Sims' 1303/4.2) get in over Jerome Bettis (1429/4.9), Curtis Martin (1487/4.0/14 TD), Clinton Portis (1508/5.5/15 TDs), Marshall Faulk (1282/4.1/522 yds receiving), Edgerrin James (1553/4.2/17 TD/586 yds. receiving), Eddie George (1368/4.1), Mike Anderson (1487/5.0/15 TD), etc.
And although some will say it's heresy, I wonder if Taylor would be anywhere near No. 1 if he didn't play in NY. Rushing the passer and getting sacks was his main claim to fame, but the reality is that several of his contemporaries put up pretty comparable sack numbers:
Taylor -- 132.5 in 184 games
Rickey Jackson -- 128 in 227 games
Kevin Greene -- 160 in 212 games
Keith Doleman -- 151 in 232 games
Andre Tippett -- 100 in 151 games
Derrick Thomas -- 126.5 in 167 games
If these other guys had played in NY, I wonder if they'd be talked about in some of the same ways that LT is. While Taylor is sometimes credited with causing the sack to be recognized as an official NFL stat in 1982, I think that had a lot to do with the NY Sack Exchange, with both Gastineau and Klecko getting more than 20 unofficial sacks in 1981. Having LT doing his thing in NY that same year didn't hurt, but contrary to some people's belief, the 3-4 defense with a pass rushing OLB existed before LT (see, e.g., Dolphins' 53 defense with Bob Matheson and AJ Duhe)
