I think Poe is a good late first round prospect, but I just don't see him as a 3-4 NT. No way. He's a quick, gap penetrating lineman.
Here is a clip of Memphis v. Tennessee. It's not a Poe highlight, but you can see him (#74) standing out to a degree on the Memphis line. He's chasing down RBs from behind and penetrating, etc.
Mismanaging the clock.
