I would be ok going WR in the second or later if he was the highest rated guy on our board and Dallas simply thought he was too good to pass up. However, we would also be fine without drafting one too, IMO.
Dez and Williams at the starting positions is better than fine. Harris/Beasley in the slot would be a terrific combo. Plus Witten/Escobar/Hannah at TE would be very, very good.
So in 3 WR sets, we would have Dez and Williams out wide, with Harris in the slot and Witten at TE. That is some very good targets for the QB.
In 2 TE sets, Dez and Williams would be out wide with Escobar and Witten playing TE.
We would be just fine with those guys to throw to.
