Griffin is small, but he is far from slow. He doesn't have the moves of Barry Sanders, but he can sneak through holes very well. Anderson will still get carries, and Garrison will get a few hundred yards. The Broncos have been saying they'll get their rushing yards, but they never say with who for good reason.
Julius Jones has competition from this little known Pro Bowler named Eddie George. In fact, looking at the Cowboys current depth chart, Jones is THIRD string.

Yes, Jones is worthless, the Bears will be lucky to claw out 5 wins this season.
Chris Brown, I can't put down. I have him on my fantasy team and I was very content with him.
A true dark horse though is Brian Westbrook. The Eagles finished second in rushing last year with their running back by committee with the three backs all having over 450 yards. Westbrook was the best of the bunch with just over 600. Put on the spot he could choke, fall into the ignored pile, or shine. If he shines in the Eagles rush heavy offense, he could pile up some insane stats.
