I think this should be a class for all the fans. For Carr to get the boos was out of line. I also believe when there is a bad product you have the right to voice your opinion, but also boo the o-line, the playcalling, the penalties, the fumbles, not just one guy. I know we all want to see the Texans have the highest rated passer, rusher, receiver, super bowl champs, etc, but there is more details to the game than what most people see as the final product! The o-line has focused so much on the run in the second half of the season since DD has come back, they seem to not care at all about pass protection, for anything further than a 5 step drop! Don't boo a guy running for his life, boo the guy who caused him to do so!
