Redskins running back Clinton Portis believes that it's only a matter of time before he has a breakout game this season. "It's only a matter of time before I have a 200-yard game," Portis told the Washington Post. "It's only a matter of time before I have a 150-yard game. It's only a matter of time before I get two or three touchdowns. It's just the fact, when's it coming? I know it's coming. But when?" Clinton Portis has rushed for 183 yards, at 3.9 yards per carry through the season's first three games.
