Caddy is obviously never going to be Tiki Barber or Marshall Faulk as a reciever, but he's not Shaun Alexander either . The two guys on this offense who are threats to make a big play with the ball in their hands are Galloway and Cadillac. If you can't get Cadillac going in the run game, then you have to find a way to get him the ball in space.
Let me ask you this. Would you rather continue to see Pittman recieve those screens on 3rd and 15 plus, or do you think Cadillac may actually be able to pick one up some time? that maybe if you just gave him a try behind some reasonable blocking with a QB that could handle some heat, he could have an even better chance to do it on 1st and 2nd down too...
In space, I would love to see Caddy catching a ball and running to create. In space, there is zero gravity, and he would be able to do such a thing.
Seriously, it just looks like he has a hard time with catches, even pitches. He has to see the ball in, usually while turning his body at an angle not conducive to just running immediately afterward. He was never asked to be a receiver, and in the WCO, suddenly he sees it. He needs to have that ability, and it isn't easy for him. One of the reasons why guys like Fabian Washington aren't wideouts despite excellent lateral quicks, and vertical speed. Caddy just lacks hands. He lacks the ability to catch and run.
He might be able to learn this skill, but he hasn't as of yet.
Watch the games, he never turns a catch into something good. He just catches it and gets planted.
He is concentrating too hard on catching the ball.
