The Naval Academy conducted its final preseason intrasquad scrimmage yesterday, leaving Coach George Welsh "very unhappy" over the results.

"Our mental attitude isn't right," said Welsh. "We seem to have a lack of concentration out there. I can't remember the ball being on the ground as much as it has been the past two weeks."

Welsh was referring to a rash of fumbles near the end of the first half. The only touchdown of the first half came when defensive back Bob Wilson stole the ball from running back Steve Callahan and romped 55 yards to score.

The second half consisted of the jayvees running Virginia plays against the varsity. The Mids open against the Cavaliers on Sept. 16 in Charlottesville.

Junior fullback Larry Klawinski, a two-year starter who missed spring practice while playing lacrosse, ran with the No. 1 offense this week.

Bowie State College Coach John Organ has been pleasantly surprised by the performance of the Bulldog offense as it prepares for tomorrow's opener against St. Paul's (at Bowie State, 2 p.m).

"We've been able to move the ball, which is unusual for us," commented Organ. Last season's Bulldog squad was so offensively inept that a defensive end was the leading scorer going into the final game.

But Organ does not expect the same situation this season, especially following a scrimmage against Johns Hopkins last week. Freshman quarterback Blaine Saddler impressed everybody by tossing four touchdown passes. Fullback Ron Evans, who missed seven games with a knee injury last year, demonstrated the extent of his recovery with a 35-yard touchdown romp.

Defensive backs Keith Faison and Keith Williams have looked good enough in practice to alleviate Organ's preseason worries about inexperience in the secondary.

"We feel we are two-deep at every position," Organ said, adding that the entire squad is healthy for the opener.

Over at Georgetown, Coach Scotty Glacken is happy about the 60 players remaining on the squad, especially since the final roster showed 37 men a year ago.

Twenty-five are freshmen, the best turnout of first-year men in Glacken's reign. The standouts of the group include 200-pound fullback Vince Zenga and quarterback Jim Corcoran, who at 6 feet is the tallest signal-caller in Hoya history, according to sports information director John Blake.

Glacken moved last year's starting defensive tackle, John Boland, to fullback, replacing his graduated brother Jim, and leaving end Kevin Boland as the only representative of the family on the defensive line.

Bob Sitz, starting his third straight season at quarterback will lead the Hoyas in tomorrow's scrimmage at Anne Arundel Community College.

Timothy Lee, an all-Met from Theodore Roosevelt who was listed as the third-string Howard center, strained knee ligaments in practice last week and is expected to be out until midseason.

The young Bison, who have just 12 seniors on the squad, most likely will start a pair of newcomers in the offensive backfield. Donald Canady, a 205-pound transfer from Santa Monica Junior College, and freshman Wesley Lewis, a 175-pounder from Sarasota, Fla., seem to have the inside track. Lewis has been particularly impressive at halfback.
