really depends on how CJ2K perform
if he keep playing like his week1 and week2, or just slightly improved, then you lost the trade
upgrade from knox to marshall is not enough to justified the lose from brady to schaub
i don't think you necessary win the trade, i think you just gambled it, and could possibly win the trade is CJ2K back to his old production
but just by preseason projection, you do win the trade, however, week1-week2 is making brady the hottest QB.
you need some potential player from waiver wire for you flex, like D.Moore, Helu, D.Nelson and if lucky, maybe D.Thomas and F.Jax (which i highly doubt it)
fix your QB with Fitzpatrick or Newton, which are probably taken already but still on bench, make some trade and grab on of them if possible
