The Redskins Donald Penn to work his way back into game shape and play a solid left tackle or to have Geron Christian develop in a hurry. The Redskins' line clearly is better with Trent Williams at left tackle, but there's a definite chance he won't play here again. It'll be on those two to make it work and they've both shown in two preseason games that a lot of work remains. Otherwise, the Redskins will have to do something they haven't done in a long time: Give the left tackle extra help.
