What to think of Michael Crabtree?

Thanks to last year's holdout and this year's neck injury, Crabtree has played in exactly as many career NFL preseason games as I have have. Which would be zero. Team captain Vernon Davis had enough of Crabtree acting like a diva and the two were exchanging words and people stepped in to separate the players before it escalated into a full on brawl towards the end of the preseason. Crabtree didn't win any points from his teammates this preseason and I'm sure he lost a lot respect from his team and coaching staff. Davis was sick of watching Crabtree not participate in preseason games and practices because Davis knew what the outcome would be and that is the timing and confidence would be off between Alex Smith and Michael Crabtree. It has already showed  in the first two weeks with Crabtree only catching 3 passes for 44 yards and 0 Touchdowns. Miss-communications between the two have already resulted in interceptions & incomplete passes. It looks downright ugly between the two. For someone who was drafted around the end of the 4th round or in the beginning of the 5th round in most fantasy drafts, he is probably one of the most disappointing players so far this season. The problem is he is having his preseason training camp right now over the first 3-4 games of the regular season before he is up to where he should be.  I drafted Crabtree in the 5th round and I am going to hold onto him a few more weeks because I think he will start producing after week 4 and he should be a solid receiver there after. If he gets into week 5 and he is still catching between 1-3 balls a week I will probably cut my losses and drop him and move on.
