I see nothing offensive in what he said about the women, (believe me I have heard many coversations like that sitting in my seats),
It doesn't matter what you and I think. A certain segment of the viewership found it offensive and that's enough for him to apologize.
Like it or not, announcers are held to a different standard. What you and I might say in our seats is not being broadcast to millions. It was just a dumb thing for a public person to say.
BTW, he is not incredibly inciteful as an announcer. He was not known as a very bright guy when he pitched and it seems like that was fairly accurate. His lone insight is basically "Throw More Fastballs and Strikes."
And on top of it, Dibble is a b*tthole. I had my 12 year old son and his friend with me one time at the stadium and we ran into him in the concourse after a game. They asked him for his autograph and he didn't even slow down. Simply said "Sorry, guys" and kept going. OK, maybe he was in a hurry but take 30 seconds.
