That"s not the common usage of the term.
#1 WR with elite contested ball skills is what you want.
There was a huge difference in Dez and Irvin. One was an elite route runner. The other one just ran around randomly while Romo ran around waiting for him to get a little separation before throwing him a jump ball.
I know I'm using the possession receiver term incorrectly. What I tried to get across was, rather more of a big WR, then a small speedy one. A receiver like Kenny Golladay from the Lions is the type I hope they target, not a Tavon Austin, Tedd Ginn.
Yes, I understand. You want a #1 WR with elite contested ball skills. That's usually a big WR; although, Steve Smith was a better contested ball WR than many bigger players.
