Redskins Coach Mike Shanahan said he intends to use Josh Morgans loss of composure in St. Louis as a teachable moment for the rest of the team.Shanahan also said he does not intend to punish Morgan after the wide receiver drew a 15-yard penalty for tossing the ball at Rams cornerback Cortland Finnegan as the Redskins mounted a comeback bid.Youre always going to play your best players, the guys you think give you the best chance to win, Shanahan said. What youre trying to do is make sure it doesnt reoccur again for your whole football team. Thats the difference between winning and losing, keeping your composure.A lot of these veterans set these guys up, Shanahan continued. When you take a look at the film and you see a guy push you in the face, and all of a sudden a guy loses his composure and the other guy is walking away. And you throw the football at him and hes laughing, you understand what hes doing. Its part of a young guy growing up.Asked whether Morgan apologized to the locker room, Shanahan said he did not.There was no need to, Shanahan added. You take a look at the film and there were probably eight other scenarios that we used in the game beside that one about keeping their poise and composure. Thats what you have to learn.Morgans penalty turned a 47-yard field goal attempt into a 62-yarder, which Billy Cundiff missed badly. Shanahan revealed Monday that the Redskins would have gone for the first down (on fourth a foot) had Morgan not been flagged.
