Joe Theismann was right the last time he dispensed advice on who should have his old job as starting quarterback for the Washington Redskins. Should Mike Shanahan listen to him this time?In October, the Redskins pulled Rex Grossman after he had thrown four interceptions in three quarters of a game against the Eagles. John Beck went in and played respectably, and he was announced as the starter two days later.Theismann took to the radio and said: I just dont agree with the decision to start John Beck, on 106.7 The Fan. He said Grossman got a little bit of a quick hook.Beck started the next three games, and the offense was dead in the water. Shanahan saw one of his teams get shut out for the first time in his 18-year career as a head coach when they lost to the Bills, 23-0.The switch to Beck turned out to be a bad decision. Now, Theismann says the Redskins are about to make another one.Speaking again on The Fan, he was asked his opinion of the possible marriage between Peyton Manning and the Redskins. He said: Its not a good idea, its not a bad idea its a horrific idea.When Theismann spoke of Beck starting, he did praise Becks ability and said he didnt think it would be an issue if the Redskins were to switch back to Grossman. But he left himself with no wiggle room in talking about Manning.Havent we seen this act before? And by the way, if you get Peyton Manning, dont you have a concern about protecting him? Dont you have a concern about who he throws the football to? Theismann said.If were going to be 5-11, if were going to be 6-10, lets do it with somebody whos learning as he goes, instead of guys that have been here, making mistakes.That last part presumes that the addition of Manning would do nothing to improve the Redskins record. Mannings Colts posted at least 10 wins every year but one since 1999. The team collapsed to a 2-14 record with Manning out this season.When speaking of the switch to Beck, Theismann said finding a quality starting quarterback is the biggest problem that we have had in Washington in the last 27 years, basically since I left.It seems Theismann is opposed to one particular solution to the problem. It will be interesting to see what he has to say if Manning does indeed join the Redskins.Rich Tandler blogs about the Redskins at www.RealRedskins.com.
