Nice line up! The only thing I would even consider changing is possibly going with Gore .. even at Seattle .... over Doug Martin. The Rams run defense isn't all that shabby and DM has more or less flamed out the last couple games, plus we don't know if TB has bought the farm and will be going through the motions now that they are out of contention?
Most TB players seem to dislike Schiano and might not want to play hard for him now that the season is basically over anyway.... its a risk. Even if DM is playing hard, will the Oline also give it everything they have or go through the motions like they did last week?? Id avoid DM for all of those reasons.
AJ Green is possible too in place of DM at flex RB/WR, but only because Ike Taylor is out and the rest of the Steeler's CBs are a little banged up. Your choice.
Otherwise sit tight and you should win your title game ... Good luck!
