Well it certainly took the Phillies a long time to get to that point. Bowa was only forced out when Kapler became manager and Charlie still managed to become the hitting coach during that time. And I would say Gillick remains influential (and, I believe, still has his tiny ownership share) but less so now that Dombrowski is here. He certainly recommended MacPhail (and MacPhail actually did play a key role in recruiting Dombrowski and was still allowed to run that entire search, easy to forget that now!)
I think Barber's influence is actually the most shocking thing. Apparently he has been Scott's most trusted guy in that role behind the scenes (whereas Clarke and Holmgren's influence was always explicit).
What's dumb is Briere really is just Hextall 2.0, part insider, part outsider, younger and less experienced than Hextall but not necessarily a out-of-nowhere person. Obviously Hextall had his shortcomings but we also know he wasn't truly allowed to do his job, and was forced out in part for not sucking up to that trio... so now we're hoping they will finally do what they should have in the first place.
