Maybe it's different in NFL, but a lower levels the target area on wide receiver on higher throw over coverage are about one helmet over top of helmet, not where their fingertips are at top top of their highest jump, that would require throwing the ball where it arrives about 5ft over the head of the receiver. Go back and see where CJ or Graham or Colston high point balls arrive.
So, Graham doesn't bring us a different mismatch than Cooks? I understand what you're getting at, and I too think his height is overplayed considering all the receivers I've name that are his height or shorter, but to act like an extra 7 inches is nothing is just silly to me. It's a difference when throwing to Graham and it will be a difference when throwing to KB.
I prefer Cooks and didn't want the Saints to touch KB in the draft, but trying to marginalize his size just doesn't make sense to me. He's 6'5" with 35" arms and a 32" vertical. That's nothing to try to marginalize.
