The only way Crabtree will thrive is when he puts in the work with his QB's and sadly, he's never done that. Smith got roasted for throwing an INT during Crabtree's first game after the holdout. Only there was one thing that was very obvious during the play. Smith, getting criticism for not throwing to a spot on time, did what he was told. He threw to Crabtree's area. The ball went out fast, right to the spot, no Crabtree. He cut his route, fell down and got up in time to tackle to guy who intercepted the ball.
I'm not sure how Crabs not wanting to be a Niner has anything to do with what happened this year. You don't go out and break or re-break your foot to get out of working out during camp or preseason. However complex the guy's head is, tough. They can do fine without him and if he continues to be a problem, trade him for another 7th round draft pick.
There's too much good about the team to be dragged down by the likes of Crabtree.
They can work him in to the offense when he comes back, or they can put him on the bench. All we've seen during preseason is vanilla plays, with the occassional long absent slant play. What they really trot out for the Seachicken game might be a lot more fun than we've seen to date.
