The Pirates broadcast guys are good.
Brown seems like a fan. But at times, he forces "enthusiasm" where it doesn't belong.
Neverett is your vanilla, by the book play-by-play guy. That's a pro, and a con.
Wehner is knowledgeable, and willing to call out errors and mistakes. A bit boring though.
Blass is boring. Homage to the 70s and yinzers. The only thing I like about him is that he has a good sense of humor, and a good sense of story telling.
Walk is best of the bunch. Understands baseball, can easily explain baseball, and is even-handed when talking about baseball. The last part is refreshing since many guys are forced to toe the Company Man line.
In the case of Wehner and Walk, they lack (or odd sense of) humor. It's a bit unattractive, especially in a color guy. It's the only redeeming value of Blass. I don't mind more strait-laced or rigid personality in doing the job for a play-by-play guy. It's not so nice in the color guy.
And the guy in Chicago "Put it on the board... YES!" is actually pretty good. That booth feels like a couple guys watching a game in the local bar. Has that sense of good humor and personality that makes you (the fan) feel like you're enjoying the game with some buds.
I love when Steve climaxes, "Oh, Pedro!"
