San Jose (Calif.) Bellarmine Prep linebacker Michael Clay, one of the top weakside backers in the West, added another offer on Wednesday, and his first from the Big 12.
"Colorado just offered me," said Clay. "That's nine overall."
The Buffs join UNLV, Oregon, Utah, Fresno State, California, Washington, New Mexico and Washington State in offering Clay.
Last weekend, Clay earned all-combine honors at the UnderArmour/Scout.com Combine in Los Angeles.
During his 2007 junior season, Clay had 110 tackles and earned WCAL Linebacker MVP honors, and he helped lead the Bells to the WCAL title.
