My guess is it's gonna be ESPN's attempt at a sports version of The Daily Show/Real Time with Bill Maher?
"Keith Olbermann, whose daily late-night program debuts Monday, Aug. 26, on ESPN2, will make his first SportsCenter appearance in 16 years tonight during the 11:00 p.m. ET show. Olbermann will provide an essay concerning Alex Rodriguez’ return to Yankee Stadium tomorrow night. “Olbermann” will air Monday-Friday at 11 p.m. live from New York studios."
