Rex Grossman

A day after Rex Grossman described his confidence as “at an all-time high,” Washington Redskins offensive coordinator Kyle Shanahan cast further uncertainty on the veteran-yet-turnover-prone quarterback’s future role with the team.

Shanahan, who last week said that Grossman needs to eliminate his turnovers, on Thursday praised the quarterback’s aggressive nature. But at the same time, Shanahan said he would have no problem going with a quarterback that has no experience in his system next season. The offensive coordinator also acknowledged that the Redskins remain in need of a franchise quarterback.

“No, not at all. You don’t need a guy that’s experienced with your system,” said Shanahan, who is in his second season with the struggling Redskins after directing the Houston Texans to the ranks of the league’s offensive leaders in 2008 and 2009. “When [Matt] Schaub came into Houston in his first year, he played at a very high level. I don’t think it’s a system that takes a long time to learn. You can get better at it, but everyone in the league runs similar plays. You’re going to run what they’re good at and the better they are, the more you keep doing it.”
