Even if he's a special player, the point is that he would be behind in the depth chart because of "chemistry and knowledge of the play book"
I don't care who you are, if you have the talent, you play them- this is why I don't buy the depth crap bronco feeds us. He digs his own grave by only playing guys like carter and leaving players like burt, dye, etc. On the bench when they would be providing the very depth he is complaining about. I'm not saying they should be the feature players, but game experience is more valuable than reps in practice, and by not getting these guys in, we virtually start over every year with the "depth" issues
