Trade: Watkins and Gore for Demarco?

I’m pretty stacked at WR (green, keenan, crabtree, maclin, watkins) and thinner at RB (gurley, abdullah, gore). Both Gore and Watkins are on my bench and if healthy, Demarco would start. But i’m concerned about his hamstring injury. Should I accept the trade and take the gamble on Demarco? I’m more worried about lingering injury than I am Henry taking the job.
