Tabler and Buck, for all their faults, actually have good chemistry. The flow of their broadcast is good and they don't step on each others toes. That said, it's like listening to 2 old guys sitting in the row behind you. And you can hear them babble on about a bunch of stuff that is wrong and it's unnerving but you don't/can't say anything to correct them.
But like I said, they do have good chemistry- so maybe Schulman upsets that chemistry a bit for you? I think he's pretty good otherwise.
