"Washington Redskins offensive coordinator Kyle Shanahan has cast further uncertainty on quarterback Rex Grossman's future with the team after he said the club remains in need of a franchise quarterback and will try to find one this offseason.

Shanahan — who last week said Grossman needs to eliminate his turnovers to succeed — praised the quarterback's aggressive nature. But at the same time, Shanahan said he would have no problem going with a new quarterback next season, even if the quarterback has no experience in Shanahan's offensive system.

"You don't need a guy that's experienced with your system," said Shanahan, who is in his second season with the Redskins after directing the Houston Texans' offense 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."

Grossman played as a backup for Houston in 2009 and then came to Washington on a one-year deal last season. He ended up unseating Donovan McNabb for the final three games of the season and beat out John Beck for the starting job this season. Grossman has a 5-7 record as a starter this year, but has thrown 19 interceptions to 15 touchdowns and has lost five fumbles.

The Redskins' offense ranks 16th in the NFL, averaging 334 yards per game, but has mustered only 18.5 points per game (26th) while turning over the ball 34 times (fourth-most)."
