I live in NY and watched almost every game LT played, he was dominate in every area: pass rush, defending the run, even in pass coverage. People labeling Parsons in the same breath as LT is completely laughable. Throw out the sack comparison, it's a different game today as team's only passed about half the time when he played.
Parsons is a very good pass rusher, but he has 1 career sack in the playoffs. He stats early on compared to late in the season are drastically worse, which could suggest he shouldn't be used as a full time DE.
I'm not saying Parsons isn't an elite player in today's game, but when you chose to compare him to the best ever to play, it's not fair to Parsons. Win a Defensive MVP, hell a league MVP then he can start to be comparison. Those were things that LT accomplished plus 2 SB's.
I heard some on this board also say early in the season that this was a generational defense. That was even more crazy assumption.
