Hey all and thank you for checking out this post. So who should I start for my semi-finals; LT, Maurice Morris, or Ronnie Brown? I have been going with LT all season but he looked terrible the last couple of weeks. Ronnie Brown is also terrible but is facing Buffalo, a favorable matchup. Maurice Morris is facing TB, also a favorable matchup. So who do I go with? The rest of my lineup is as follows:

QB: Orton
WR: Branch, Boldin, C. Johnson
RB: Hillis, Brown?
D: Steelers
K: Josh Brown

BN: Fitzpatrick, LT, Maurice Morris, Anthony Dixon, Jeremy Maclin, Tashard Choice

Thank you for checking this out.
