Here is what we will be talking about at Redskins Park this week:Rex or Beck?For the second time in seven weeks we wait to see if John Beck or Rex Grossman will be the Redskins starting quarterback. Mike Shanahan said that the announcement will be made after practice on Wednesday but dont be surprised if word gets out at some point that morning. Most expect Shanahan to make the switch and go with Beck but that is far from certain.Shuffled O-lineWith left guard Kory Lichtensteiger out for the season with a knee injury and left tackle Trent Williams out for at least a couple of weeks with a high ankle sprain, we know there will be changes on the offensive line. The question is, who will be playing where? The only player we know will be in the same spot he was at the start of the Eagles game is right guard Chris Chester. Jammal Brown could swing to left tackle in Williams absence with Sean Locklear, who went in on the left side when Williams went out on Sunday, playing right tackle. It seems likely that they will stick with the interior line shuffle that took place after Lichtensteiger went out with Will Montgomery moving from center to left guard and Erik Cook playing center. However, Shanahan did not commit to staying with that arrangement.Cam NewtonThe Panthers quarterback has cooled off considerably since his historic start to the season, when he became the first rookie to pass for over 400 yards in his first two games. He still is on a pace to pass for over 4700 yards and at it seems like at least once a game he makes a play that has everyone wondering how did he do that? The Washington defense will have to be ready for plays like those and be ready to take advantage of the opportunities for turnovers that also are inevitable. He has thrown at least one interception in five of his six games and he has thrown a total of nine.The running gameOr, more specifically, the lack of one against the Eagles. They came into the game allowing 140 yards a game on the ground. The Redskins mustered just 42 yards and 12 of those came on one John Beck scramble. Ryan Torain and Roy Helu combined to carry 12 times for 28 yards. The Redskins pattern this year has been simpleif they run, they win. They are averaging 34 carries for 147 yards in their three wins and 18 attempts for 54 yards in their two losses.Do you have a question about the Redskins?
