Yes, I agree, they all do have some kind of negatives. A lot of Chops actual negatives is that PSU swapped out players a lot, to the tune of Chop only getting 30% of the defensive snaps (not just him).
Breaking it down further:
Chop: 303 snaps
Latu: 535 snaps
Turner: 647 snaps
Verse: 586 snaps
So, he had nearly half the snaps of all the top edge prospects. With his over 20% pass rush win rate, it would be expected that he would have at least doubled his sacks and hurries given the same amount of play time as the others. He is superior in every metric to Turner and also happens to be the youngest of the group (by exactly a month over Turner). In fact, he is only beaten by Latu in the metrics and Latu is older and has a neck fusion.
While I initially hated the idea of taking Chop, I've come around. The kid needs to be on the field and getting into a rhythm to get results. I think Latu is the better player but has far more risks and is 2 years older with more wear.
I would not be mad if they ultimately decided Chop was who they want, I'd be actually quite happy if they did that with a small trade down.
