Couple things....
I like JJ, but I would trade him for Ronnie Brown in a heartbeat.
As far as the game went against New Orleans, how many times did you watch the game? I'm just curious. Because the first time I watched the game, I was majorly disappointed with the run game. But then I read somewhere that the Saints basically started putting 8 and even 9 men in the box after the first drive. So I went back and watched. And that is exactly what happened. What does that do? It puts WR's and TE's in single coverage. Our QB's pretty much had their way with the defense through the air. You take what is given.
Does the run blocking need to improve? Sure. But just focus on the big picture to see if there isn't a reason why something is happening. Parcells said when Carter was here that one day we would pray teams would blitz and stack the line. If Owens is healthy, that day is here. Because Owens, Glenn, and Witten will shred that.
