Just reading some of Francona's bio... seems he and Buddy Bell were pretty tight in their days with the Reds and Bell named him to his coaching staff while in Detroit.
Also, I gotta think Francona and Don Cooper are very familiar with each other since Coop was the minor league pitching coordinator while Francona managed Birmingham for 3 seasons.
Given those facts, I'd say Francona is likely to be our new manager if he's not looking for top-tier $$$.
