I think I like that trade. My reasoning is that LT, McFadden and Hillis all are doing great now, but we can't be sure about any one of them down the stretch this year. All have backups right there waiting, McFadden has a bad hammy now, Hillis is banged up this week and S. Greene could get more carries down the line. Plug in Rice and you have two real solid RBs and then at least one out of LT and McFadden should work out to give you three really good backs, maybe even all four. Moss and Harvin might be hard to play together, especially when S.Rice comes back, but I like Wallace and Floyd a lot too. Hope this novel helps you!
