I'm not saying he will or won't be, but it wouldn't shock me if Crabtree were a bust...
I would be shocked if he were a bust. At worst I think he may not live up to expectations, but not a "bust". Barring a drug, alcohol, or violant off the field issues, he seems to have too much ability to be a bust.
I dunno.  Seems to be a lot of X factors no one wants to talk about.  For instance, he turned out to be shorter (much so) than originally thought.  There is no real evidence that he has breakaway speed, and let's be honest, the system he played in at TT was VERY receiver friendly.  Yes he put it on the Horns, but I'm not altogether convinced that their secondary was that good...
He could be a Steve Smith, but he could just as easily be a Charles Rogers.
