Opinion on a trade?

[Furrski]

In my ppr league I am starting DeSean Jackson, B Marshall, and Welker at WR, leaving Boldin on the bench. I start R Rice and Ryan Grant at RB, and have Slaton as my only other RB. Ryan Grant and Slaton scare me, so I've been floating Boldin for a RB.

My depth at WR is good, also having K Walter and Crabtree.

I've been offered Mendenhall, or Joseph Addai for Anquan.

Week 11 is our deadline. I've been holding Boldin on my bench all year where he does no good. Addai seems like a good haul, right?
