One good season, a history of injury and a lack of elite speed does not spell monster deal.
If the Niners want him, they'll be able to sign him and he'll be happy to stay. Otherwise, where's he gonna go? Dallas? Pffft!
Don't make the mistake of construing the team's mind-bogglingly inept handling of their WR situation, and the QBs lack of experience in advancing the passing game, as meaning that Crabtree is irreplaceable.
Irrespective, if the Coach/FO don't wise up fast with respect to evaluating and stocking their offensive skill positions, this team does not have a bright future.
They inherited Gore, Crabtree. Hunter and Davis. Botched the drafting of AJ, Johnson (cut) and LMJ (who is marginal, at best, so far) and seem paralyzed when it comes to evaluating and stocking the WR roster (See KW, BMoore, etc.). Niners are lucky that Kap is even on the roster. They were willing to trade him away to Philly for, which at the time time seemed, a lesser pick than they used to draft him.
Personnel dept needs to step it up.
