There is a debate in Washington over whether QB Rex Grossman has a legitimate chance to make a claim on the Redskins’ starting job for next season. Some observers think head coach Mike Shanahan and offensive coordinator Kyle Shanahan were setting up Grossman to fail when they named him the starter in Week 15, benching Donovan McNabb. But there are others who feel Grossman will have a chance when they line up again in 2011, provided he continues to perform well. After all, the Redskins’ long-term QB solution likely isn’t on the roster, but Grossman could be the buffer to whichever young quarterback the team adds — and this is a very strong possibility — in the offseason. Grossman has played well before for stretches, going 15-4 during the Bears’ Super Bowl run in 2006, even if he ran hot and cold throughout that year.
