The Top 25 team recruiting rankings for the class of 2006 had few changes now that the players are enrolled and taking classes at their respective colleges.

Southern Cal will be counting on an early enrollee this season. Tim Floyd will employ the services of Daniel Hackett, who played with the loaded Southern California All-Stars this summer. Hackett graduated a year early in order to help ease the loss of Ryan Francis, who was killed in the offseason in Louisiana.

Hackett's addition helped push the Trojans into the top 25 at No. 21 overall. He joins an already solid class for Floyd and company. USC signed Taj Gibson, Kevin Galloway, Kyle Austin, Kasey Cunningham and Dwight Lewis earlier in the recruiting period.

USC and Kansas State could make a splash at the semester break with two big-time additions.

Southern Cal is holding a verbal commitment from former five-star wing Davon Jefferson. Sources tell Rivals.com he could join the Trojans in December once he becomes fully qualified. Jefferson has instant-impact capabilities and could make a splash with pro scouts in his probable short stint at USC.

Bob Huggins and his staff could add five-star prospect Bill Walker from Cincinnati's North College Hill. Walker was ruled ineligible by the Ohio High School Athletic Association after it was learned that Walker competed in varsity athletics as a freshman in Kentucky before enrolling at North College Hill as an eighth-grader. Sources say Walker is taking the ACT this weekend and could join the Wildcats in late December.

Other notable changes to the top 25 include Memphis' addition of former Florida signee Doneal Mack. Mack will pair with Willie Kemp in the backcourt, giving the Tigers a dynamic 1-2 punch for the future. Memphis cracked into the top 25 at No. 23 with Mack's addition.

While Florida lost Mack to Memphis, the Gators added former N.C. State commitment Dan Werner. The National Champions close the class at No. 20 in the country.

Villanova signee Kraidon Woods is spending a year in prep school and will not be counted in the 2006 class. The Wildcats remain at No. 14. Texas A&M is in the same position with center Brandon Webster. The Aggies slip a spot to No. 22.
