This is the least of my complaints about Joe Buck because I have zero problem with natural sound and I don't need gimmicky catch phrases or a signature call.
The primary reason Gene Elston was fired by Drayton McLane in 1986 was for simply uttering "There it is!" and then allowing Glenn Davis to run to the bag and seal Mike Scott's no-hitter while the crowd screamed and the players jumped. Contrast Elston's call with Milo Hamilton's screeching throughout Hank Aaron's 715th home-run trot and I'll settle for something in between.
IMHO Milo spoiled Hank Aaron's 715th home run by screaming as Aaron went all the way around the bases. If he had just STFU after "..and its Henry Aaron," and let the event play out I could stomach it.
Instead, I prefer Vin Scully's or Curt Gowdy's calls of the same home run. Particularly Scully.

But, Drayton wanted screaming and gimmicky catch phrases, so he went with the polar opposite of Elston by hiring Milo. Yelling and ego-maniacal to a fault. Just not my taste.* But, there was one other Astros announcer that would talk non-stop during a game and that was Bill Brown. Brown was very knowledgeable, and he's a nice guy, but he could not tolerate so much as three-seconds of dead air without speaking, and therefore spoke incessantly. He knew his stuff, but Brown called television like it was radio and it was annoying.
* ironically I will always utter or think "gotta go get-em Astros!" a la Milo when they head to the 9th on the short end of the score.
