The difference between Dorsey and Berry is that Berry actually seems to value the input of other people. He's brought in a couple of former GMs primarily to pick their brains, he embraces working with the analytics side, and Stefanski certainly has a voice as well. He recognizes that the best teams work as an actual team, not a dictatorship. He gets the final call, but if you have good ideas, he's willing to listen.
Dorsey was the guy who tossed a binder full of analytic data in the trash the second DePodesta left the room. Dorsey seems like the type who always thinks he's the smartest person in the room. When he's right, it works out really well (Chubb, Baker, Ward), but when he's not it can be disastrous (Kitchens, most of his picks other than the three I listed above).
