There four major players that will become free agents in 2015. Kaepernick, Aldon Smith, Crabtree, and Iupati.
In addition, Miller, Hunter, Dorsey, Skuta, and Culliver will be free agents at the same time.
It would be good if we could keep three of the four big names(A Smith, Kaepernick, Crabtree, and Iupati.)
If I were Baalke I would have already begun contract talks with each one of these four.
The sooner the front begins, the better.
My guess is that we extend Kaepernick and Aldon Smith rather soon--during training camp.
We do have to make sure that Aldon stays in line during the off season.
I think that signing Iupati or Crabtree will be more complicated.
Of the others, I think signing Miller, Hunter, and Culliver will be the priority.
The front office has a bunch of work to do. I do not envy them.
