You want me to trade a bellcow back that's had his bye week for a guy with an advantage in a time share that hasn't?
That aside, I value having White available as a flex option over the 2.5 extra points Dalton would give me over RG3, and I'm not about to trade the league leader a WR2 for a guy he is literally never going to start again. Enjoy your Manningham, I guess.
