Here we go. The "he doesn't block, we don't need him" narrative. "He doesn't make contested catches". Put it up there with Metcalf's 3-cone and Deshaun Watson only throwing 49mph at the combine. Everyone is an expert. In the Co-USC video you posted, he won a contested catch in the 2nd or 3rd clip. A catch in the endzone on a very poor pass. I don't know where you're getting this from? Last year it was "Metcalf can't get separation at the NFL level." A far more damning criticism than one's willingness to block, and it was false.
Laviska Shenault is going to shine in the NFL. He can catch, he can run after the catch, he has speed. Stop complicating this. He's an obvious talent. It's as plain as day.
It is true. Tre is very good. I don't throw the term shut down around to just anyone. Revis and Sherman are the last shutdown corners this league has seen. They did it for an extended period of time and QBs avoided their side of the field. Tre ain't that. Not yet.
And take the blocking questions with a grain of salt. Every year it's a new ridiculous claim to NOT draft offensive talent on this board. It's weird.
