I'm just very concerned with how high cut he is... and the fact he had 2 major knee injuries plays right into those concerns.
He may have tested well athletically, but the lower half functional strength and stiffness is worrisome on tape. I could see him being a solid 3-4 OLB, but we'd be drafting him to be that war daddy RE... something I highly doubt he ever delivers on.
I just see enough red flags that make me hesitant, and I don't believe the upside is enough to justify the risk. Let someone else figure it out.
