If he's going to do anything, it's going to be this week or Week 17 against SF (which probably doesn't count for your fantasy playoffs).
The Houston offense is just terrible because of their line. If STL doesn't pressure Carr, he'll find Johnson a few times. Another thing going for them is the possible loss of Bulger (although I really hope he's OK
). Without him in there, the pass attack of the Rams doesn't look as menacing even with Holt/Bruce/Curtis all healthy.
