If anyone has any information about doghouses or disharmony, either share it or don't bring it up. But needing a reason for a TB who performed well but only moved up the depth chart because of injuries to others who are now healthy is silly. Devontae Houston averaged SEVEN yards a carry last year playing through injuries. And Brewton was ahead of both him and Rosa to start the season before he got hurt. There is zero reason for people to be speculating about trouble brewing under the surface.
As I said, if the OP actually knows something and feels like sharing it, feel free to do so. But neither speculation on this, or just stating a fact if one is known without giving the board any reason to accept that you know something, is incredibly unhelpful.
