Torrey Smith for McGahee? WHIR 100%

[saemick]

I needed a RB bad. Here's my roster

QB: Romo, Ponder
RB: Foster, Martin, Tate, Miller
WR: Julio Jones, Torrey Smith, Antonio Brown, Hartline, Denarius Moore
TE: Witten, Hernandez

The guy who has McGahee also has McCoy & Lynch, so he has some depth. Am I giving up too much for McGahee?

Should I accept, decline, or counter with: Smith & Witten for McGahee & Tony Gonzalez?

Also, another manager offered me Michael Bush for Denarius Moore or Hartline... Should I do that as well/ instead?
