I think to answer that one has to go by their past rushes per game. Last yr they ran the ball fewer than most teams: 25.7 rushes per game. Faulk averaged 19 of those carries a game.
In 2002 they were dead last at 21.4 attempts per game. Faulk saw an avg of 15.7 of those.
Now that precedence is known, we can better guess what to expect this yr. I see maybe 25-26 rushing attempts a game this yr. Faulk should get the slight majority of those. One can reasonably expect Faulk to get about 15 rushing attempts per game with SJackson averaging around 10.
