Navy football Coach George Welsh put his team through its first full scale workout of the preseason today and came away less than satisfied with what he saw.

"We're not practicing well right now and it showed in the scrimmage," Welsh said. "We are behind where I think a veteran team should be at this moment. Again, the penalties and mistakes kept us from being consistent. We shouldn't have had all those penalties, particularly the number of them we had in the first half."

Welsh was slightly happier with the offense in the second half, particularly the ground game, led by running backs Mike Sherlock and Duane Flowers and quarterback Bob Powers.

Flowers, a sophomore from Rockville, picked up 142 yards on 24 carries while Sherlock added 89 yards on 26 carries.Powers had 66 yards on eight carries, including a 41-yard touchdown run and hit seven of 14 passes for 56 yards.

Hampering the scrimmage was the absence of six players because of injuries or illness from the first two units, including Gregg Milo, honorable mention All-America defensive back, out with a virus; Steve Callaham, leading rusher, bothered by a knee injury, and defensive tackle John Merrill, out with a pulled leg muscle.
