Channing Tindall's issue is not talent, Intensity, or heart, it's instincts.
Instincts can't exactly totally be taught, but with experience, a player can still play more knowledgeable in what to expect, and might be happening in certain situations, but it takes time.
What makes Tindall special is that though his instincts may not be top level to know where to go, or what to do in certain situations to get that one step earlier to stop the play, Tindall may take the slight micro second more to figure it out, but with his speed can and will put him in position to make plays as long as he stays in control, and starts allowing the experience to start making it 2nd nature to him.
It may take him a little longer to get on the field then others, but once he does...LOL, it's going to be as fun to watch our Defense, as our Offense.
