Francona is a great manager in the way that you'd apply the definition in 2016, where the MANAGER term is especially appropriate.
From the outside, he resembles what would qualify as a great boss in our (as in the people whom these various posts' typing fingers belong to, who have jobs and lives which they neglect to post on the Sox) own lives at our real jobs. Nice guy, very smart, very well informed on all of the job functions (since he's done it all, player, coach, player personnel), good humor but a straight shooter. Would not publicly embarass you, and was really good at creating an office which was a nice place to work and for you to be productive. And he was good at keeping the other bs to a minimum (media savviness very important here).
