I totally agree with this and so does Football Outsiders:

Williams strikes me as a slightly worse version of Mike Evans. Very good prospect but lacks the elite skills to create mismatches on his own. I'd rather Ross if they're going WR in Round 1, but frankly maybe Howard would be the better pick than either of them in terms of pure versatility and mismatch-creating ability.
All of that said - something tells me that McDermott comes from the Dave Gettleman school of using high picks on the front seven, which I've always preferred...
