Yeah, I'd say
LT''s one and only generational impact on the game remains in tact.
And that he still has no peers.
In my opinion, Reggie White is the greatest defensive player of all time, not Taylor. And it's not really that close. This is an argument like the one that claims Jim Brown is the best RB of all time, when Barry Sanders was clearly better than any other RB to play the game. This is not a knock on either Taylor or Brown. But both have been eclipsed by other players.
I would argue that Taylor had a bigger impact on the NFL, highlighting the importance of the offensive tackle position. But the importance of the OT position has been enhanced by changes in the rules, which has diminished the run game, and with the prolific passing games of today, increased the importance of wide-outs and quarterbacks. Taylor played in a different era, when stopping the run was just as important as rushing the passer. That;s like arguing the difference between Jerry Rice and Bob Hayes - both HOF wide receivers. Bob Hayes caused the entire NFL to change because no one could guard him one-on-one. So, Hayes had the bigger impact on how the game is played. But Rice is clearly the best wide receiver of all time - except maybe Randy Moss would have been better if he had two HOF QB's to play for his entire career.
One thing to think about when comparing LT to Parsons - which started with a lot of other people in the NFL, not me - is the style of defense they play in. It would be interesting to see how Parsons played in a full-on 3-4 defense., and also how he would be deployed if running games were more a part of the NFL today. One of the reasons I think Parsons is compared to LT is that he has the ability to beat Olinemen with both power and speed, and his ability to beat double teams when rushing the passer. That is why he gets compared to LT. On the other hand, LT, despite him destroying QB's, played a more complete LB role, where Parsons has been relegated to playing primarily as a pass rusher - more in the mold of DeMarcus Ware than Lawrence Taylor.
I still say that LT's performance was enhanced by his use of cocaine - much like that of Hollywood Henderson in the 1970's. LT was also allowed to play with more fury, unlike the defensive players of today. LT would get fined out of his mind in today's NFL, much like Roy Williams, after 5 straight Pro Bowls to start his career, became irrelevant after the NFL outlawed his style of play. Roy Williams would easily be another Cowboys' HOF player if he played in the era of Ronnie Lott, and was allowed to go head hunting like Lott and Taylor did in the 1980's. In many ways, it's unfair to modern players to compare them to the great defensive players of the past, simply because the modern rules prevent us from seeing just how ferocious they might be if not constricted by the modern day "safety" rules that limit the effectiveness of defenses in today's NFL.
I'm not saying that Parsons is better than LT. I am saying that it would be interesting to see how Parsons could play if he played under the same rules that governed Taylor, and was hyped up on performance enhancing drugs like LT.
