First, im not mad at what you think, i really dont care you arent the Hc.
Second i dont believe is a everydown back, i think he is wat he was at the beginning of the season, a 1st and 2nd down back.
Third When you have only 10 carries, and you break 1 or 2 of them for 10+ gains, your YPA will be high. Am i saying that barber is not a good back, no. But to say becuse his YPC are higher, and JJ's is lower it proves your right is once again silly.
Fourth, by the Romo effect i mean that instead of staying with a consistent running attack, and then passing, the coaching decided to come out throwing, throw, throw, throw, and then when all else fails, run the ball, then throw some more.
fifth, you once again missed another segement ofmy argument. When you playing from Behind, because your defense cant stop anyone, your not going to easily be able to run the ball well enough to even get a RB into a game, in order to even make plays. JJ made a career long run of 77 yards to start of the game, and because the defense starting faliling quick fast and in a hurry, the next thing you know its 42 -17
In conclusion you have the roles switch backwards, Barber is wat he is, a change of pace back, He has been one in highschool, college, and the NFL. JJ has always been the top runner, and has proven he has reason to be, when not befalled by a couple if injuries. If health was your concern then you would have merit, but its not. So therefore you dont.
