Another thought strikes me at this particular moment in time, Dr. WEO (may I call you Dr. WEO?). Clay's background was as a running back and as such, always a good runner with ball in hand.
Croom on the other hand, former wide receiver. And LT is a big dude. I think they're both more natural high-pointers of the ball than Clay has ever been.
It's another reason O'Leary is gone- what he did best is catch it and run with it, he was never a strong traditional in-line tight end. And with these other TEs around, maybe Clay can get back to some of that H-backy RAC stuff, always been the strength of his game. Making O'Leary totally expendable
