Boler's always bugged me a bit, with just the way he tries to understand everything in football terms (one and out). But I did a thing a few years back where I got NBA League Pass, and listened to the opposing broadcast on all the road games. It gave me a lot more appreciation for our broadcasters, the others were by and large just awful. Don't mind him so much anymore.
Harp I thought was pretty good in the first couple years, he had a lot of good insights when he was fresh from playing. Lately it had seemed to me like his commentary had just devolved to a running dissertation on the quality of the game's officiating.
I don't mind Holly. Tells a story well. Cadence seems pretty natural. It still seems like she's trying to figure out when to talk, like she and Boler sometimes get into these awkward things where they both are trying to say something at the same time and are kind of both mad at each other for interrupting but trying not to show it on the air. They'll probably figure it out more as they go.
