Taufaasau from New Mexico Military Institute in Roswell, N.M., committed to UW Sunday after they visited Laramie and the UW campus over the weekend.
Taufaasau (6-2, 289) is from American Samoa and was a First Team All-Western States Football League pick this past season as a sophomore. He had 40 tackles, the most on the team for a defensive lineman, including seven for loss and he also forced three fumbles.
UW's three starting defensive linemen in 2009 were seniors. The only experienced linemen that return are a pair of nose guards in junior Alex Stover and sophomore Mike Purcell. Stover won't be able to go until summer because of a groin injury.
Patrick Mertens was a walk-on true freshman last fall who will go on scholarship in 2010 and count toward UW's 2010 recruiting class. He will be a redshrit freshman this season.
Taufaasau is the sixth defensive line recruit in this year's class.
"(Defensive line coach Jerry Montgomery) told me I have a good chance to come in and compete for a starting spot for next season," said Taufaasau, who will be able to play two years for UW and plans to be on campus this summer.
Taufaasau said Troy and Western Kentucky also offered him scholarships, and he also was recruited by Utah State and Division II Tarleton State out of Texas. He also said UW was the last school he plans to visit before the Feb. 3 signing date.
"I'm going to be a Cowboy for real," he said.
Taufaasau was also considering: Troy, Western Kentucky, and Utah State.
