I’ll let the rest of TBD posters praise Lamar. He is genuinely great.
But Allen is the better overall player and always will be.
Once Lamar loses his speed, it’s going to become much more difficult for him. What makes him a prolific passer (rather than just a very good passer) is the threat of him taking off around the edge. It is such an incredible advantage. DE’s always have to maintain contain and DT’s can’t over-pursue, and it’s very hard to commit to man because as soon as you turn around he runs.
