As a Dolphins fan, I don't think any non-Dolphins fans would enjoy the 'Fins announcers. They are very biased and almost call the game like fans instead of announcers. They don't really toe a fine line on being at all a neutral party. I enjoy them though!
Denny doesn't need to be in a broadcast booth. He has no voice for it! He doesn't need to be a head coach either, so I really don't know what's left for him. Maybe comedy on Raw Dog..that was a pretty funny bit when he did that rant after losing to be Bears last year! You wanna crown 'em, them crown their ass! But the Bears were who we THOUGHT they were! And we let 'em off the hook!
