My theory re JJ is rather simple. First off Parcells obviously likes what MBIII is doing cause he's getting more carries while JJ is getting less. In tough situations, it's MBIII who goes in and not JJ. I like the 2 RB alternating system Parcells employs, but despite JJ 4.0+ average, I don't think he's contribulating his share of the yards. I'm not sure MBIII has enough speed to be a legit starting RB which is why Parcells continues giving the ball to JJ. I also don't believe we can win a SB with JJ as our starter nor MBIII cause latter will wear down & not be explosive enough when we need him later in the game. But apparently we will stick with what we now have for rest of this season.
In 07 will be Tyler Thompson's 3rd season and we all know what that means. He's gotta show more in preseason so he becomes effective part of our backfield (picks up the blitz, decent receiver, etc) or he's gone. His return avg won't keep him on this team cause it looks like Austin can get the job done. I'm taking the long way of saying both JJ & TT may not be around next year unless both step it up.
If Parcells sticks with JJ & MB as our twosome next year (unless JJ shows lot more then he has done this year), then Parcells isn't doing his job. I'm not saying JJ will be cut but JJ could find himself the #3 RB with MBIII #2 and a new #1 brought in--whether it be a RB selected in the draft or a FA. Remember we don't need an Edgerrin James but we do need a #1 RB who produces more then JJ has in our twosome system.
