Has anybody ever given thought that the reason they don't throw downfield is Carr's fault?
When your RB has 11 catches in a game with not many screen passes called, that's on the QB to make the play downfield. I highly doubt every WR on the field are running 8 yard hitches as Carr continues to dump off to DD. Now either the WRs aren't the getting the needed separation or Carr can't find them when they do.
You can't put everything at the feet of the OC/HC. I've been following a conservative offense in Austin for a number of years. A conservative offense is WR screens, slants, 5 yard outs. The Texans do not run a conservtive offense. They just need the players to execute better.
