But the Cougars also did not have any explosive plays out of the backfield. Junior Carl Winston's 11-yard run was a team high.
Wulff attributes that to the offensive line's performance, particularly junior-college transfer Taylor Meighen, who made his first start with senior center Andrew Roxas (ankle) sidelined.
"Taylor Meighen in his first career start maybe didn't play as well as we all would've liked," he said, adding that Roxas will not practice this week but he hopes to have him back next week.
Wulff said the Aztecs also benefited from playing a few teams that run the option recently.
"They were as sure of tacklers as we've seen in a long time," he said. "I thought how well they tackled had an impact on the ballgame."
AS DID SDSU'S running back. Sophomore Ronnie Hillman finished with 191 yards and four touchdowns on 32 carries. Wulff said he liked how his team played against the run until the third quarter when Hillman had a 59-yard run and "the floodgates kind of opened of us."
"I think a little bit of that maybe was being worn down," he said.
WSU faces another accomplished back in Colorado's 5-foot-6 senior Rodney Stewart, who rushed for 1,318 yards last year.
"The Stewart kid is a very quick back," said Wulff, adding that Hillman is more of a slasher and has good balance. "He's different than Hillman. I would be surprised if we see a better back this year than Hillman."
The Buffaloes (1-2) defeated Colorado State 28-14 on Saturday. They lost their opener 34-17 at Hawaii, but in their only game at Folsom Field they went into overtime against California before losing 36-33.
Wulff said the coaches will watch Colorado's game Saturday at Ohio State, but he is more concerned about his team for now.
"We've got to finish in practice really well and learn how to play a fourth quarter," he said. "You're not going to learn how to be successful until you've been in those situations. We've got to develop some confidence and consistency late in games."
