Can I ask how old you are? Have you heard him across his career or just the last 10-20 years? He absolutely IS a legendary sports commentator. He is easily the most studied, knowledgable commentator across a wider array of sports than anyone else I've seen. Sure he's getting near the end too, but he has earnt his current status and standing more than most of these clowns.
I'm 34 and used to love Bruce's work back in the 90s. He was the king. Unfortunately the poster you quoted has it spot on.
His commentary these days consists of:
-homoerotic growls and moans
-repeating the same word several times in a row
-making a comment in the form of a question ending with "ay?"
-lately, he's taken to replacing the word "the" with "that" e.g. off that step, down that line, on that left
