NBA play-by-play:
Marv - He's still my favorite. I don't think he's the best, but I love his style and I enjoy listening to him (especially if he's next Fratello).
Jim Durham - My 2nd favorite. I can't believe the Bulls let this guy go and replaced him with Dore. Merriam-Webster should use this as the example for the word "travesty."
Kevin Calabro - ScottMay, good call, as usual.
Honorable mention for whoever Denver's tv pbp guy is. Actually, that duo is quite good.
There's not many NBA color guys I'm overly impressed with. Fratello is good when paired with Marv, because of their chemistry, but without him, he's average. I feel Doug Collins is a bit overrated, as well. He's good, but he says a lot of things that don't make sense and sometimes talks just to talk, which is annoying for any color guy.
College color:
Bill Raftery - My absolute favorite color guy of all-time in any sport. Not only does he know his stuff, he gives actual analysis and is funny and entertaining...all at the same time. I'm constantly quoting him during games. "Oooh, the kiss!" on a bank shot is my favorite. I agree it's also unbelievable that he's been #2 behind Packer for as long as I can remember. (Also, here's an example of what makes Raftery so cool: he also does NBA analysis on NBA-TV. And he knows his NBA just as well as college. Impressive.)
Clark Kellogg - He gives really good analysis, whether he's doing color or studio work. One of the keys to being good, in my mind, is NOT coming off as an arrogant know-it-all (I hope Billy Packer reads this). Both Kellogg and Raftery do a good job of this.
College play-by-play is like NBA color guys to me; nobody that impresses me much. Dave O'Brien is ok (ESPN) and Jim Nance used to be, but that's all that comes to mind (I'm probably forgetting about someone).
UNfavorite college play-by-play:
Brent Musberger - Sorry DKG, but I think Musberger is the most overrated announcer of all-time. I can't stand his melodramatic style and his over-the-top attempts at hipness and humor. Horrible.
Dick Enberg - Just annoying and not good. Thank god he was relegated to doing a short, video "vignette" during the final four.
