He has elite separation, the dude is a speedster, he just has some stuff to work on. The skills are there.
No, the
athletic ability is there. It's the skills and perhaps other necessary talents that are missing. He's currently a shorter Braylon Edwards without the route-running ability. That's not a good player.
I think one of the most common mistakes -- maybe
the most common mistake --fans make when evaluating players/prospects in the NFL and NBA is assuming that raw talent consists solely of athleticism, and that almost everyone has the ability to learn the necessary skills if they possess the athleticism and work ethic. "Just give him more time learning the position and he'll be great!"
The problem is that there are raw, essentially unchangeable aspects to "talent" that aren't athletic. Basic hand-eye coordination is one of them. Intelligence -- at least the kind of athletic intelligence that lets you process the field and the space/time/speed relationships of yourself and other players quickly -- is another. Some dudes are never going to have good hand eye coordination, and simply don't have the "feel" or athletic intelligence for the game. And they won't develop it no matter how long they play.
Some guys just catch everything that is thrown their way. They have an instinctive feel of how to wall off defenders from the catch, or how to run a route that maximizes the QB's window. That's how some slow, relatively unathletic guys can have very good careers in the NFL anyway. Of they at least have the ability to do it correctly after being told to do it. They just
know that if you run a sideline route, you cannot be forced too close to the sideline or the throwing window will be non-existent. They know the "feel" of a zone, and when to sit in a hole in coverage. But some guys just don't. You can explain it to them 50 times, and they'll never truly "get it". But for the guys that do "get" it -- sure, there's a learning curve where they will get better at it over time. But you usually can see that they have those basic abilities pretty early on.
The thing is, those aren't just things that "gamers" do. You can demonstrate and polish those skills just as well in practice. And if you're not doing it there, there's no reason to assume you'll magically start doing it in games.
Granted, Calloway is young, and more importantly, we really have very few WR bodies anyway. But at least as of now, I don't think he's demonstrated either the skills or the talent for us to assume that it's just a matter of time until he corrects his flaws.
