Should retired fighters be allowed to be commentators without any qualifications?

[FinitoxDinamita]

Anybody who is to be on a microphone in front of live TV should know how to speak properly, ex fighters or not. I enjoy listening to Paulie and Tarver, Roy too.

Abner Mares, Lewis, Ward, and Bradley just got the gig because of their credentials inside the ring.

Yes, they should be allowed to comment, it depends on the fighter and which one he is going to comment on - if they have a bad opinion or history with one of the fighters, they shouldn't. It is another thing if they can deliver good comments, but bad ones are there even from professional commentators.
