"Let's make a bet," Favre told members of the University of Southern Mississippi baseball team on Thursday, the Biloxi Sun-Herald reported on its website (www.sunherald.com).
"You go back and I go back."
Southern Mississippi, Favre's alma mater, played in the tournament last year and is ranked among the top 30 teams in the country this year.
"I don't know - yet," said the NFL's all-time passing leader, who has retired twice and returned, first to play for the New York Jets in 2008 and then the Vikings in 2009.
