Are you threatening people? Really? What are these "real and immediate" consequences? You'd beat someone (or something) up for disagreeing with you? Maybe give them a tongue lashing they won't soon forget? That last sentence seems to imply so...
So any announcer who talks about himself is bad? What about when the game's boring and conversation meanders to the mundane briefly?
By your logic, you seem to imply that any announcer who makes any mention of his past exploits is by default a bad announcer.
Ergo, using your logic:
Bob Uecker = Bad announcer (he refers often to his mediocre career as a player)
John Madden = Bad announcer (heck, when wasn't he talking about himself to some extent?)
Hey, any former player or coach is a bad announcer!
