Syracuse is a unanimous No. 1 in The Associated Press college basketball poll for the second straight week while SMU moved into the Top 25 for the first time in almost three decades. The Orange (23-0) received all 65 first-place votes from the national media panel Monday. Arizona, Florida, Wichita State, San Diego State and Villanova remained second through sixth. Wichita State (25-0) is the only other unbeaten team in Division I. Kansas moved up one spot to seventh and Duke jumped three spots to eighth. Michigan State and Cincinnati round out the Top Ten. Wisconsin and Ohio State, Nos. 21 and 22, both returned to the rankings after a one-week absence. SMU, which beat then-No. 7 Cincinnati last week, moved in at No. 23, the Mustangs' first ranking since the next-to-last poll of 1984-85, a season they were ranked as high as No. 2. Oklahoma, Oklahoma State and Gonzaga fell out of the Top 25.
