The matchup Saturday between Colorado State and BYU features footballteams which are unbeaten in conference play.

CSU is 3-0 in WAC play and 4-2 overall, while 13th-ranked BYU is 2-0 and 4-1. In fact, there are four unbeatens, but barring ties only two will emerge from weekend action unscathed. The other two, New Mexico (1-0 and 2-4) and 23rd-ranked Wyoming (3-0 and 6-0), face off in Laramie.In another league clash this weekend, Texas-El Paso (0-3 and 2-4) entertains Hawaii (1-1 and 2-2).

Air Force (3-3) plays at eighth-ranked Notre Dame (3-1), and San Diego State (2-3) travels to UCLA (2-3) in non-league games. Utah is idle.

New Mexico faces a tall order. The Lobos have lost their last 18 WAC road games, while Wyoming is riding a seven-game winning streak dating back to the finale of 1989.

UNM snapped a four-game losing streak with a 48-28 decision over UTEP last week, while Wyoming outlasted San Diego State 52-51.

"We're mostly a one-back team like San Diego State and Washington State (two recent Wyoming opponents), so from looking at film we've been able to get a feel for how Wyoming adjusts," Lobo coach Mike Sheppard said.

Both quarterbacks - UNM's Jeremy Leach and Wyoming's Tom Corontzos - are coming off fine performances. Leach completed 21 of 32 passes for 284 yards and three TDs in what Sheppard called "his best game of the season." Corontzos hit on 20 of 32 for 421 yards and three TDs in what Wyoming coach Paul Roach termed "the best day of his career."

UTEP, one of only two teams without a WAC victory (Utah is the other), had its highest point of the season in last week's loss to New Mexico, but only half of the points were generated by the offense as the Miners managed just 218 total yards. Freshman Roy Ross returned a kickoff for a TD, and the special teams accounted for another score on a blocked punt.

Hawaii got its running game cranked up last week, generating 263 yards, but the Rainbows' big-play man has been Jeff Sydner, the WAC's leader in all-purpose running. Sydner ran for two touchdowns, caught a TD pass and returned a punt 82 yards for another score in last week's 44-3 rout of Maine.

Air Force is catching Notre Dame at an inopportune time, one week after the Irish were knocked from the No. 1 spot in the polls by a 36-31 loss to Stanford. Notre Dame has won the last four meetings after four straight AFA triumphs. Junior Rob Perez has won the starting quarterback job for AFA.

San Diego State came close to beating UCLA for the first time last year. Bruins coach Terry Donahue figures that will help his team when the schools meet Saturday night.

"I don't think we'll take San Diego State lightly, the kids who were on the team last year know we were fortunate to beat them," Donahue said. "San Diego State's coming in here capable of beating us."

UCLA has beaten San Diego State 10 straight times and leads the series between the schools 12-0-1.
