ESPN is ramping up its push for the Mike Golic and Trey Wingo morning radio program with it set to debut at the end of the month, but the network continues to be mostly mum about the TV show that made “Mike & Mike” worth killing off.

Mike Greenberg’s morning TV show has been pushed back from Jan. 1 to the spring, and ESPN has not officially announced the co-hosts, though Michelle Beadle, Jalen Rose and Booger McFarland are fully expected to land the roles. The risk and importance of the show — amplified by the acrimonious split of Golic and Greenberg — is coming, though, with “Mike & Mike” ending next week.

“There’s going to be intense pressure to make it clear it was worth spending money on these people and their shows when the company is cutting costs elsewhere,” a source told Sporting News.

ESPN has gone all-in, building a South Street Seaport studio for the program as it continues to cut costs with the widely publicized layoffs in April and with more reportedly set to come in the near future. As Golic and Wingo begin their program, Greenberg will be off air, with a spokeswoman telling the website that his exact role during that time is “still being discussed.”

“The break will do him and everyone good,” one source said. “He’s going to be maniacal once this gets going because of the pressure to succeed.”
