I would say stay with Crabtree and then Watkins. D Jax 3rd and then Nicks. Of course you would have to check on game day to make sure Crabtree plays. Crabtree has a solid relationship with Kap and should be the "Go-To" guy for Kap. Watkins is iffy with EJ at QB, but you gotta have faith, lol.
Ya I would have to say the safest and highest ceiling would have to go to D Jax followed by Watkins, Crabtree and ending with Nicks.
