Johnson & Johnson Knee Should I Start Mario Manningham Or Calvin Johnson?

Should I start Mario Manningham or Calvin Johnson? - johnson & johnson knee

Both are listed as questionable. Manningham has a sore shoulder, Johnson has a bum knee. Manningham wants to play, but it seems that Johnson is looking for excuses not to play. Of course, Johnson is a better WR and goes against the Rams, but I'm not sure what he wants, or to produce points in the week. Let me know what you think.
