I agree with this. If he’s a good route runner and has reasonable lateral quickness and agility, I would keep him at WR.
Tight Ends need to be able to block well to stay on the field on running downs, and have to block linebackers at that. TEs are typically 30-50 pounds heavier than Harbor is now, so he’d have to pack on weight, and probable lose speed. As a WR, imagine Harbor being assigned to block 190lb cornerbacks and free safeties. He’d be pancaking them! WRs take less big hits than tight ends, and on average get bigger contracts than TEs.
All that being said, he would also project as a very good DE, given his measurables. But DEs are more about explosive power, and Harbor obviously has both explosive power and top end speed. DEs get beat up alot more than WRs.
Actually, it’s pretty crazy that we’re even talking about a prospect that could be either a WR or Edge Rusher.
