Tucson has been anything but friendly to UCLA's football team.

The Bruins have lost four consecutive games at Arizona Stadium, and all came with an abnormal amount of suffering and turmoil.

Karl Dorrell and Rick Neuheisel had their fates as coaches sealed in 2007 and 2011. UCLA had a perfect season soiled in 2005. The Bruins walked away embarrassed after the Tucson Tussle, an ugly brawl in 2011.

Once more into the breach go the No. 16 Bruins, who travel to Tucson for a game Saturday with no margin for error. Another loss probably will keep UCLA (6-2 overall, 3-2 in Pac-12) out of the conference championship game. Arizona (6-2, 3-2) is in the same situation.

"It's a tough environment to play in," UCLA Coach Jim Mora said. "They are going to do their best to get in our heads. That is what happens when you go on the road."

A summary of the Bruins' last four nightmarish trips to play the Wildcats:

2005

UCLA entered the game ranked seventh with a three-pronged offensive attack: quarterback Drew Olson, running back Maurice Jones-Drew and tight end Marcedes Lewis.

"We came home with our tails between our legs," Olson said.

Arizona, which finished with a record of 3-8, rolled to a 52-14 victory.

"We were coming off an emotional comeback win at Stanford and just got smoked," Olson said. "We were not focused and they were hyped."

Tucson remains a head-scratcher to Olson.

"Arizona always has a lot of L.A. kids," Olson said. "It's a big deal when UCLA or USC comes to town."

2007

After UCLA lost, 34-27, to an Arizona team that finished 5-7, Bruins linebacker Christian Taylor made a pointed postgame comment: "It's just about finding some players in here to play football with."

Looking back, Taylor said it was more who the Bruins were than who they were playing.

"I never felt we put it together on a week-by-week basis," Taylor said. "You never knew which version of us would show up."

Dorrell was fired and Rick Neuheisel was in charge the following season.

"That was the story of my whole time at UCLA," Taylor said. "It was frustrating."
