I've got a similar question and every time I write a response, I suggest using Foster! Everything seems to be right, matchup, poor play of the other to RB's for Houston, etc. Obviously Houston will be throwing the ball quite a bit, but if a lead can be established they might turn more to the run. Also, it seems every RB on the roster has had a crack at handling the ball and this week will be Foster's turn.
Forsett has stepped in admirably, but appears to be back to sharing time.
I'd go with Ganther as the #2.viewtopic.php?f=19&t=465308
