I'm just looking at the stats, theogt, no conspiracy theories here.
Parcells' average YPC for his main running back is a lot lower than you think. It's so persistent it has to be deliberate. And very often his secondary runners have higher averages than his main back. Some examples follow.
these numbers come from here:

Ottis Anderson - 1989, played 16 games, 325 carries 1023 yards 3.1 ypc
That year Dave Meggett averaged well over 4. But Ottis Anderson was the main runner. This was a good NYG team and Ottis just sucks compared to JJ.
Ottis Anderson - 1990, played 16 games, 225 carries 784 yards 3.5 ypc, in a year when Rodney Hampton averaged 4.2 and Meggett averaged 7.5 yards a carry.
Curtis Martin - 1995, played 16 games, 368 carries 1487 yards 4.0 ypc, in an exceptional year by BP standards. Meggett averaged 4.2 ypc.
Curtis Martin - 1996, played 16 games, 316 carries 1152 yards 3.6 ypc. No one ran much better than that in 1996.
Curtis Martin - 1998, played 15 games, 369 carries 1287 yards 3.5 ypc. Both Leon Johnson and Sowell averaged over 4 yards a carry.
Curtis Martin - 1999 played 16 games, 367 carries 1464 yards 4.0 ypc. Parmalee averaged 4.9 ypc, and Richie Anderson averaged 5.2 ypc.
Let me point out that on a YPC basis, JJ is having a better season than any of these listed. The only seasons I can think of that are better are the 1985 and 1986 seasons of Joe Morris and perhaps JJ's rookie season itself.
