I think Goldson, Boone and Goodwin may be the odd-men out when all is said and done. Given that Crabtree and Kaep seem to have such a rapport with one another, it makes sense to view them as part of any future planning. Davis is good and Iupati is a definitely a keepers.
With the way Kaep feeds Crabtree the ball, I think he'll be highly likely to re-up when the time comes with San Francisco.
Kaep -- locked up
Crabtree -- locked up
Iupati -- extension looming
Depending on the money:
Davis -- extension looming
