Huge trade oppurtunity need help fantasy football?

Slaton is done as the primary back in Hou after all of his fumbles. 5 total fumbles and 4 in the last 5 games. With that said Pierre is a stud and you upgrade at RB. Shiancoe is no Gonzalez, but Favre loves him and will continue to throw to him, and Garrard is better than Cell, but you have Manning so who cares? I'd do it.
