This is basically what Krang is saying. I don't see it but I have been wrong many times.
its always sketchy comparing a draftee to a HoF player.
Last season in college Watt had like 68 tkl 21 TFL 7 sacks
Robinson had like 44 tkl 14 TFL and 8 sacks
similar...but Robinson played against tougher competition.
6'5 300 pounds...power to speed....
the only real difference is it seems like JJ's arms were about 2 feet longer when he got behind the LoS...I think JJ was stronger but much of that could be 280 Vs 320...which can be changed with decent trainers
then of course there is technique... not saying the kid is canton bound,...just that he could develop into a major force and be a cornerstone for a long time. he seems to have the right mental makeup
