Is Cadillac truly No. 1 RB?

Posted by ESPN.com’s Pat Yasinskas

The Bucs listing Cadillac Williams as the No. 1 running back on the depth chart is a great story. I’m just not sure it’s entirely true. Williams

At this time of year, depth charts don’t always tell the whole story and we won’t know exactly what the Bucs are doing at running back until the regular season starts Sunday. Listing Williams as No. 1 might be accurate. But there’s also the possibility that designation is a reward for Williams and motivation for the rest of the team.

Williams did a fantastic job coming back from his second major knee injury in two years. He’s also a veteran and a very popular figure in the locker room. Coach Raheem Morris very well may start Williams on Sunday against Dallas and the running back could play a significant role.

But I wouldn’t go starting Williams on your fantasy football teams. I don’t think the Bucs are going to give him 25 or 30 carries right off the bat. Even if Williams truly is the No. 1 running back, the carries are going to be split three ways, with Derrick Ward and Earnest Graham also involved.

Morris has talked about a 2-2-1 system where one running back would play two series, followed by another running back for two more series and a third running back for one series before switching back to the starter.

That’s not a bad idea because the Bucs have three quality running backs and they all need carries.
