Mike MacIntyre has been very adamant about giving his starting quarterback Connor Wood ample opportunity to prove that he was worthy of the position.
Mid-way in the first half of play in Tempe Saturday night, the Buffs coaching staff made the decision it was time to go a different direction.
But Sefo entering the game against ASU Saturday night, it burns his red-shirt, something that has remained intact until the game against the Sun Devils.
"We thought it was the right time," MacIntyre said after the game. "Sefo will be the starter for the rest of the season unless he doesn't play well."
Wood threw one interception and was ineffective in the Buffs first four possessions.
Early in the week when asked, MacIntyre said he was unsure what direction he and his staff would go in regards of whether to burn or not burn Liufau's red-shirt.
"Connor hasn't had a passing grade the last four games," MacIntyre said. "Connor has done some great things for us, and isn't totally responsible for us not playing well, it's definitely a team thing. We feel that Sefo is ready to play, he has continued to get better in every practice and we knew we needed a spark in the game."
Liufau guided the Buffs 80 yards on 11 plays to give CU their first score of the game on a 10 pass play from Sefo to Nelson Spruce.
According to MacIntyre it wasn't an easy decision in regards of burning Liufau's red shirt, but something that he and his coaching staff thought was best for the team.
"This is a young man that is very talented," MacIntyre said. "He is very bright and we feel at this point he gives us the best chance of going forward and being successful. We plan on playing and starting him the rest of the season, unless he isn't playing well."
MacIntyre was asked if he ever considered putting in Jordan Webb instead of Sefo last night.
"No not really," MacIntyre said. "If Connor had came out and played a great game and was really clicking and had to come out of the game because his helmet came off or that kind of thing we would have put Jordan in. We feel that Sefo is our future and gives us the best opportunity to build this program."
Liufau finished the game with 18 completions out of 26 attempts for 169 yards, one touchdown and two interceptions.
"I thought he handled himself really well, he was very poised and calm in a difficult situation." MacIntyre said. "This is a tough position, it's in the limelight, all of the focus is on him. We definitely feel he has a bright future ahead in our program."
