Get shorter.

"I would never use the term, 'Stand tall in the pocket,"' new Washington Redskins coach Jim Zorn said. "Then you get players standing straight-legged, and they're straight up and they can't move."

During this weekend's three-day minicamp, which ended yesterday, Zorn kept telling the 6-foot-5 Campbell to play "compressed." What the coach is looking for is a different stance so that Campbell appears about an inch shorter in the pocket.

"It's just very, very subtle," Zorn said. "Bend a little bit, and give him the opportunity to move laterally quicker than maybe what he's done in the past."

During the minicamp, Zorn occasionally pulled his quarterbacks aside after a play to demonstrate exactly what he meant. After practice Saturday morning, the coach gave a demonstration for reporters.

Zorn stood up tall, straight and rigid, with his knees locked. "It would be hard for me to get out of the way of anybody," he said.

He then slightly bent his knees, widened his stance and relaxed his hips. It wasn't a dramatic change - just enough to bring the top of his head down about, yes, an inch.

Campbell is sold on the technique. He only has to look at a past Zorn pupil to see what the benefits could be. As the Seattle Seahawks' quarterback coach, Zorn guided Matt Hasselbeck to three Pro Bowl appearances.

"It took him a while to catch on to all the things (Zorn) wanted him to do," Campbell said. "Once he got used to doing it, look where he's at now."

Keeping Campbell's head down isn't the only height-related change Zorn has implemented. He was also concerned with the level of center Casey Rabach's posterior before the snap. Zorn said Rabach needed to raise up so Campbell doesn't have to crouch down as far, allowing the quarterback to stay at more or less the same level throughout the play.

Rabach took the instruction good-naturedly.

"We're going to come to a happy medium on that, make both parties happy and go from there," Rabach said, laughing. "If raising my butt an inch or two is going to help, whatever, I'll accommodate them. It'll take a little time. It'll feel awkward at first, but we'll get it done."

Campbell is no stranger to adjusting to a new system. He had four different offensive coordinators in four years at Auburn, and this is the third offensive scheme he's had to learn in four years with the Redskins.

"Right now, there's lots of things going through our heads, but that's part of the beginning stages," Campbell said. "I'm trying to picture plays in my head, and at the same time, trying to understand technique and be disciplined, the things he wants you to do as a quarterback."

DAVIS OVERSLEEPS: Washington Redskins second-round draft pick Fred Davis did not show up for minicamp practice yesterday, having overslept on just his third day in the NFL.

The team sent security officials to track down the tight end after he failed to arrive as scheduled from a local hotel, where the rookies were housed during the three-day minicamp.

"Everybody was scouring," coach Jim Zorn said after the practice. "Nobody heard from him, so there was one of two scenarios. Either there was some real trouble and we needed to find him, or he screwed up. I haven't even got to talk to him yet. I know he has been found. I believe it is more in the 'I screwed up' category."

Davis eventually arrived at Redskins Park and met with Zorn in the coach's office.

"He just had a setback," Zorn said. "Hopefully everybody will learn from the lesson that he is having to learn right now about what it is going to take to get to a place on time, to be responsible."

Davis was the 48th overall pick out of Southern California in last weekend's draft.

NOTES: Safety Reed Doughty, whose son recently underwent a kidney transplant on March 10, missed practice after the young boy spiked a fever and was taken to the hospital. ... Minicamp ended with S LaRon Landry beating RB Clinton Portis in a 40-yard dash. The challenge came about after Landry chased down Portis on a play during practice.
