"The Washington Redskins entered Sunday's game with a game plan that called for running back Clinton Portis to spend much of the second half on the sideline. As for their plan beyond Week 3, Portis admits, "I have no idea. "If they call on me, they call on me," Portis said following Sunday's 30-16 loss to the St. Louis Rams. "If not, I got to cheer my teammates on, be the supporter that they need me to be." A running game that has been searching for answers churned out more questions in Sunday's loss. From the backfield rotation to the on-field execution, it has been the least predictable part of the Redskins' offense through their first three games. The team's commitment to the ground game is unclear, and they'll enter next week's game at Philadelphia averaging a league-low 19 carries per game. And if Redskins Coach Mike Shanahan knows how he'll use Portis from this point forward, he's not offering many hints. "We'll talk about that next week. There's a lot of possibilities," Shanahan said. "You have to evaluate the film. Can't say right now. And I would never say right now." Against the Rams, the rushing attack posted its best half of the season in the game's first 30 minutes, which was then followed by its worst. The team entered the game ranked last in the league with 107 net rushing yards through two games. Playing behind an offensive line that featured two new starters in Stephon Heyer and Kory Lichtensteiger, Washington ran for 115 rushing yards on 12 carries in the first half. But in the second half, the ground game disappeared. The Redskins had only one yard on five carries in the final two quarters against a Rams blitz that seemed to plug every hole.
