While talking to the Chicago Sun-Times from the General Managers Meetings in Orlando, Reinsdorf said Guillen would have gone to the Marlins for a specific high-level player in return, though he refused to say who that was.
"The Marlins asked for permission to talk to Ozzie, and we told them we'd let Ozzie go if they gave us a particular player," Reinsdorf told the Sun-Times. "But we knew they couldn't give us the player."
The player previously speculated by the Sun-Times in late October was Mike Stanton, but Reinsdorf told the newspaper it wasn't him. Others have speculated that it could have been Logan Morrison.
"We were never going to let Ozzie go, but if they would have given us this particular player, I would have let anybody go," Reinsdorf was quoted as saying.
"Everybody is available at a price. The only player I had that wasn't available was Michael Jordan."
Despite the tense relationship between Guillen and general manager Ken Williams, Reinsdorf said he was never forced with a Williams-or-Guillen ultimatum and doesn't believe it would ever come to that.
"That doesn't mean they'll both be here the same length of time, though," Reinsdorf said. "But I don't ever see a situation where either one of them says, 'It's me or him.'"
Guillen will be heading into the final guaranteed year of his contract in 2011. The White Sox hold an option for 2012.
