There are a lot of quality WR's in this years draft and drafting any at #9 seems too soon. Landing Johnson from UB in the 3rd or 4th sounds like better choice to me.
There are a few blue chip DL men and l would rather see them go with Oliver over a WR.
Oliver
Sweat
Hockenson
Metcalf
Would be my personal order after the Quinnen Williams and Josh Allens are gone.
