Two things, Speed.
1. Numerous pundits have commented on his pro readiness. Route running, hands, quick separation, and even his speed. Surely you’ve read the same reviews? That’s a pretty good list of WR qualities.
2. Don’t be mislead because he was drafted on Day 2 in this draft because this was no ordinary WR draft. It was an amazing WR draft.
Anyway, what Coach or QB wouldn’t love to get snaps and targets for such a WR? IMHO, Jefferson is at least a year ahead of where Reynolds was when drafted. And I think he’ll take to the NFL like a duck to water. Maybe even kinda Kupp-like in NFL readiness.
