My recollection was not very physical. As in didn’t like the contact. Haven’t rewatched film, just what i recall.
On explosiveness, some guys are explosive without being fast. Elijah Moore I think is that. Quick but not truly fast.
wr is about hands, body use, toughness, short area explosiveness. Guys who fight for the catch - not just the ball, but the position to Get to it. Haselwood was smooth and had speed but iirc not physical and not explosive.
I recall saying at the time i wasn’t that high on haselwood. (Don’t recall having a view on pickens.) It’s hard to chase oos kids for positions we evaluate badly, and we’ve evaluated wr badly.
