12 team ppr dynasty…start 2/3 RB

Current RB's: Benson, Lynch, FJax, McCoy, DBrown, Scott, Harrison, JDavis

With Benson hurt and LJ signed, and the Bills sucking a$$, I'm thrilled I get McCoy for at least a few weeks.  But I'm wondering if I should handcuff Leonard Weaver to him, especially if Westbrook is done for the year…or dare I say his career.  I would not be surprised if he at least sits out the rest of the season.

Then the question is who should I drop?  Do I give up on my hopeful Browns future backfield in either Harrison or JDavis?  Or do I give up one of my Raiders WRs – Schilens or Murphy?  I've been holding on to both hoping next year I'd be glad I did.  I could also drop Lance Long, but I just picked him up and kind of want to see how he does, especially with Bowe out 4 weeks.  I don't have very good WR depth either.

Or do I just stay where I'm at and keep Weaver on the waiver wire (unless someone else gets him of course)?

Any advice is much appreciated.

I'd drop Harrison if you really want Weaver, but I don't see long term dynasty value in either. It would be desperate times and you'd have to ahve a lot of injuries to actually start the Eagles non-pass catching RB at any point, since they are horrile at actually running short yardage and aren't really running the ball to begin with.
I think Murphy is going to be a very good WR once he has a QB that's decent and the Raiders wake up and bench DHB since he can't catch a cold. Schilens and Murphy should be the starting wideouts if there weren't outside forces in effect in Oakland.
