I'd do it. It sucks giving up AD, especially giving away two potentially top 10 rbs. But you really need the WR help, Holmes is player, we know that but he can also be very streaky since he's more of a home-run hitter. You pick up two elite WRs, two rbs with stud potential (there are reports that the new regime in SF is going to do everything they can to make the offense operate entirely around Gore). Lynch is having trouble with his suspension and whatnot, but he has shown tremendous talent, even with Jackson waiting in the wings - Lynch is at tremendous talent, and in dynasty leagues, always go for talent. Not to mention you'll still have Deangelo to carry your RB corps. Like I said, I'd do it.
