All speculation, but if I were in Theo's shoes, some managerial candidates I'd ask for permission to speak to: Bochy; Wedge; Pete Mackanin.
Remember, Bochy doesn't have a long-term deal with SF, and Theo knows him from their days in SD. Would be perfect for the job.(Speculation.)
Pretty much a no-BS person. Engenders respect from players; handles media well; great game manager.
And, of course, the X-factor in all this is we don't even know if Theo will be the Boston GM in a month, with Cubs' situation looming.
