Tomorrow at Beaver Stadium, teammates will try to knock each other up and down the field; players will switch teams in the middle of a game; and a game will take place that has absolutely nothing to do with the standings.

And if it's a nice day, 50,000 people will come out to watch.

At 1:30 p.m. tomorrow, half of the Penn State football team will line up against the other half in the 51st annual Blue-White game. The intrasquad scrimmage marks the end of spring practice, and is the first chance for the fans to see how the 2002 version of the Nittany Lions will shape up.

This year's top attraction will be the guys under center for both teams. Last year's freshman phenom Zack Mills, who dazzled onlookers with his playmaking ability while helping the Lions win five of their last seven games after losing their first four, will face off against highly recruited redshirt freshman Michael Robinson from Richmond, Va. Mills will start for the Blue squad while Robinson will quarterback the White.

Mills will have wide receiver Bryant Johnson, who pulled down 51 receptions for 866 yards last season, on his side while Robinson will line up in the same backfield as tailback Larry Johnson, who looks to be the primary running back after splitting time last season with Eric McCoo and Omar Easy.

While Coach Joe Paterno makes his annual trek up to the radio booth in the Beaver Stadium press box to become a color analyst alongside play-by-play announcer Steve Jones on the Penn State Radio Network, his assistant coaches will also take sides against each other. Offensive coordinator Fran Ganter will coach the Blue squad along with wide receivers coach Kenny Carter, safeties coach Brian Norwood and linebacker coach Ron Vanderlinden against the rest of the Penn State coaching staff.

Ganter, a 19-year veteran of the staff, will let his younger colleagues take more control of the team.

"I usually try to stay as neutral as I can," Ganter said, adding that he usually lets Carter or Quarterbacks Coach Jay Paterno or whomever he is coaching with take control of the team.

Ganter and the rest of his coaching crew will be trying to add to the Blue team's 29-19-3 lead in the series.

Among the other main attractions for the fans will be the revamped linebacking corps. Linebacker U. will return only one starter in junior Deryck Toles, who is still limited on playing time because of an enzyme disorder. Among those expected to step up are sophomore Derek Wake, who was out all of last season with a tear in his medial collateral ligament, and sophomore LaMar Stewart. Stewart's play in tomorrow's game might also be limited because of a slight knee sprain, but he still hopes to put on a show for the fans.

"It's a game, so I'm going to go out and give it my best," Stewart said. "We want to go out and try to make plays and give the crowd a taste of what this season is going to be like."

Many of the older players see the game as a fun way to end spring practice, but they remember the importance the game had for them in their early years as Lions.

"For me it's more of a chance to have a fun time," center Joe Iorio said. "After having brutal practices all spring, it's good to have a chance to have a little fun. It's a lot more important for the young guys to get a feel for what the pressure of a real game is like."
