I actually side with Koon on this one. Kid is fast, but he doesn't look like he has elite speed really. He's shiftier than I would have guessed, but I didn't really find myself saying "oh wow" when he was in the open field. Could be one of those things where he knows he's by far the best athlete on the field and is never going to get caught from behind so he rarely really goes 100%.
Either way, kid looks good and I'd be happy if he signed here. I wasn't blown away by Fuller or Stepherson in high school and those guys run by any CB so we'll see.
Also BK's track record with WRs is good enough I don't really care who he offers, I assume they can play.
