Donovan McNabb plans to study Redskins' offense from the sidelines

Although Pro Bowl quarterback Donovan McNabb will sit out Friday night's game because of an ankle injury, he still plans to work against the New York Jets at New Meadowlands Stadium.

McNabb will analyze the Jets' defense and offer advice to backup quarterback Rex Grossman, who may play into the third quarter, and third- and fourth-string signal-callers Richard Bartel and John Beck. They may need the help.

The Redskins struggled against the Ravens' formidable 3-4 defense in last week's 23-3 loss at FedEx Field. The Jets also run an aggressive 3-4 scheme, and McNabb acknowledges the Redskins must become more efficient on offense as the regular-season opener against the NFC East rival Dallas Cowboys draws closer.

"They are great teams as far as their defensive experience and the things that they do, their schemes," McNabb said in comparing the Ravens and Jets. "I think it definitely will help us continue to come together and be able to be prepared for any and everything.

"As far as tests are concerned, just kind of going back to the last game, there were mistakes in that game that we obviously need to clean up. Obviously, from myself, some throws I wanted back, we dropped some balls [and] mistakes up front."

Washington's offense against Baltimore, however, wasn't necessarily as ineffective as it appeared, McNabb said.

"There were opportunities in that game," he said. "And there could have turned out to be bigger plays than what we had. I think that's something, coming into this week, that we obviously want to get corrected and make sure we do the right things."
