Well documented by whom...the FANS? I can't remember PC/JS ever stating they absolutely must have a big WR. They've more or less cut those guys in the last 2 years or let them walk away: 6-5 BMW, 6-4 Durham, 6-1 Obomanu, 6-1 Harper, 6-5 Williams, and 6-3 Rice.
And drafting a big WR didn't seem like a priority in a draft full of them.
So to me height doesn't take the precedent over actual ability.
Beside a lot of you guys are still underrating Luke Willson, who is probably the best WR on team over 6'1.
And now that McCoy likely won't play, you're looking at one of the athletic receiving TEs making the roster who more or less are "BIG WRs"
Cooper Helfet, Rashaun Allen, and presumably Morrell Presley (since he's been practicing at TE).
