I think he's a good fit. Nice route runner, good to great hands, goes up for the ball well and adjusts to the ball (not much speed anymore, though). The question is leadership and if he's the guy to help some of the younger guys. Maybe in that case Jennings fits better on a one-year deal.
Even if the team does end up signing Crabtree, Jennings or Nicks, I hope the team still upgrades at wide receiver in the draft. I like the four top guys who figure to go top 20 in Cooper, White, Parker and Strong. At #14, I think the team has a chance at Parker although I still think he ends up in Minnesota. Strong should be there and would seem to be a real good fit.
