I don't think his game compares to Ed Reed.
Mays is a hard-hitter, and so is Reed, but Ed Reed is out of this world. He's talented in pass coverage, run coverage, returns, intelligence, leadership...Mays...we know he's a hard-hitter. We know his physical attributes are freakish, but like G said (I think it was G), there are still a lot of question marks about his game.
