Like always, making this a Reggie vs. PT thing when no one was talking about Reggie. Reggie will continue to get his carries regardless of how well he is doing because it helps to facilitate what he does best, which is catch and run. Of course PT's average per reception will be more than Reggie because he catches a lot less and is less involved in the pass game. Same reason why Lance Moore's average per catch is less than Henderson's.
In any event, we were talking about how PT is really not as effective as a lot of PT fanatics want to think he is, and his stats against the best defenses reflects that.
