LAWRENCE, Kan. - Kansas coach Bill Self went into a closed-door meeting with Kansas athletic director Lew Perkins to hash out details of a contract extension. Self, whose Jayhawks won a school-record 37 games and beat Memphis for the national title on Monday night, has three years left on a contract that pays him about $1.3 million annually. There has been speculation that Oklahoma State might come after him with a big-money offer since Self is an Oklahoma native who played and coached for the Cowboys. A Kansas spokesman said he did not know if there might be an announcement later Thursday. Self, 45, replaced Roy Williams in 2003 and has indicated several times he would like to remain, provided he gets long-term security and the school upgrades its facilities.
