What the Dodgers do is a little more subtle though.
They don't have guys rotting on the bench. They identify a player's strengths, and then use him in that scenario every single time that scenario comes up. When you watch a Dodgers game, you can see Roberts stack a lineup with platoon advantages, and then unravel that skewed handedness as game scenarios dictate. That way even the "bench players" know they are most likely going to be contributing every single night.
Meanwhile, we've seen Snit work platoon matchups with the starting lineup, but he is unable to unravel that stacked lineup in a way that is even remotely competent. This leads to instances where the Braves offense goes multiple innings suffering the platoon disadvantage because the opposing manager is able to easily outmanage Snit when deploying their BP.
