I'm split between "the old school" and "the new school" in terms of announcing. Like Dennis, I'm used to the old "professional, business-like" approach of Chris Schenkel, but I agree with Lefty that his manner of commentary would be boring today. Bowlers are, for the most part, more emotional than the "robotic days" of yesteryear.
I guess the most bothersome thing to me is that #@$%&!* "hambone" reference he makes. Otherwise, I agree that his enthusiasm is right up there with someone like Randy. The fact that he asks questions doesn't bother me. Sometimes he's a little off (ok, WAY off) on leaves and other shots, but you can't expect someone with little or no background to know everything about the sport.
And yes, Bryant Gumbel is a complete moron when it comes to announcing. He's arguably the worst play-by-play person ever to open his yap to a microphone. I watch the games on NFL Network on Thursdays/Saturdays when he's in the broadcast booth and I roll my eyes at least 10 times a game.
