For the fifth time since the college football season began six weeks ago, there will be a new No. 1 team in the impending wire service polls. Texas, which committed seven turnovers and lost, 42-11, to Arkansas, joins Michigan, Notre Dame, Oklahoma and Southern California as top-ranked teams that have been upset.

"It was no upset," said Arkansas tight end Darryl Mason. "No upset at all. I think this is the end of the domination of Texas over Arkansas and the beginning of something big."

Two undefeated Pennsylvania schools, Penn State and Pittsburgh, will be the top two teams this week, though the order will not be determined until the polls are released Tuesday.

"I'm not sure we don't deserve to be ranked No. 1," Pitt Coach Jackie Sherrill said after his third-ranked Panthers routed No. 11 Florida State, 42-14.

The Seminoles, who knocked Pitt out of a national championship last season, were the victims this time around. Panther quarterback Dan Marino passed for 251 yards and three touchdowns despite a bruised shoulder. "I thought he'd be throwing the ball about 20 yards," said Florida State Coach Bobby Bowden. "I only missed by about 40 yards." No. 2 Penn State had little trouble beating Syracuse, 41-16.

Other upsets included: fifth-ranked Michigan losing to Big Ten opponent Iowa, 9-7, for the first time since 1962; No. 8 Missouri losing to No. 17 Iowa State, 34-13, and Michigan State knocking 14th-ranked Wisconsin out of the Big Ten lead with a 33-14 victory.

Michigan, which won the Rose Bowl last season, has already lost two conference games. "We are going to play football for the fun of it from now on," said Wolverine Coach Bo Schembechler.

MARYLAND: Maryland had its best offensive performance of the season in its 45-33 victory over Wake Forest, which improved the Terps' Atlantic Coast Conference record to 2-0 (2-3-1 overall). When asked to explain the difference between Saturday's offensive success and previous failures, Coach Jerry Claiborne said, "Wake's defense wasn't as good as other teams we've played this season."

Deacon quarterback Gary Schofield completed 43 of 62 passes for 504 yards, but four Maryland interceptions, three in the fourth quarter, stopped Wake. Safety Billy McFadden had a 97-yard interception-touchdown in the first quarter that gave the Terps a 7-0 lead. And Lendell Jones' fourth-quarter interception, which Claiborne yesterday called the key play of the game, stopped a Deacon drive and led to the Terps' final touchdown.

The defense will have a similar task next week against pass-happy Duke and its quarterback Ben Bennett, who had three of his ACC records broken by Schofield.

Three Terrapins suffered minor injuries: defensive end Mark Wilson (strained calf), defensive tackle Mark Duda (bruised lower leg) and safety Wayne Wingfield (sprained ankle). Each will be examined early today.

HOWARD: Coach Floyd Keith said he has seen great improvement the last two weeks in his now-healthy Bison. Howard defeated Division II Virginia State, 26-14, at RFK Stadium and evened its record at 3-3. "We're improved," Keith said. "We've really played better. Our (Mid-Eastern Athletic Conference) game next week at North Carolina A&T will show how far we've come. But I think we're going to turn out all right."

Howard's major weapon, again, was junior wide receiver Tracy Singleton, who caught four passes for 89 yards and one touchdown. Singleton, after six games, has caught 27 passes for 685 yards and three touchdowns. He is averaging 114 yards per game and 25.3 yards per reception. When asked if Singleton had any equal in the MEAC or Division 1-AA, Keith replied, "No. We've seen some pretty good receivers but he's the best."

NAVY: The Mids' 25-10 victory over Boston College was not a surprise. But the fact that Navy did it largely with the pass was. Navy quarterback Marco Pagnanelli completed 16 of 23 passes for 183 yards and Eddie Meyers rushed for 147 yards and scored both Navy touchdowns. "Yeah, we did have a pretty balanced offense for a change," Navy Coach George Welsh said. "We've been working on the pass all the time. But we're finally getting better at it."

The Mids improved their record to 4-2, but with upcoming games against Notre Dame, Georgia Tech and Army, Welsh said, "It's too early, still, to talk about how great a season we're having." Center/tight end Bob Moore and middle guard Tim Jordan suffered sprained knees and will be examined today. Welsh said yesterday he didn't expect either injury to be serious.

VIRGINIA: The Cavaliers, who have now lost nine straight games over two seasons, dropped a 21-3 decision at South Carolina. Virginia took a surprising 3-0 lead near the end of the first quarter. But the Cavs, who amassed only 19 return yards, allowed the Gamecocks to break several long punt returns. Virginia also was hurt by punts of 71 and 74 yards by Carolina kicker Chris Norman. The Gamecocks completed only two of 12 passes.

"It was a special teams' game," said Virginia Coach Dick Bestwick, whose injury-decimated team (0-6) lost another regular, offensive tackle Fred Miles, for at least one week with a leg injury. "This loss may have been the toughest (of the season) because we played a good first half of football," Bestwick said.
