I like his play by play too. Often through a fast exchange I've heard him say something like "Oh my! That left hand caught him..." or similar... and my first thought was "What left hand? It was his right that did the damage..." Then in the slo-mo, there's a left hand doing what Joe said. True, his view ringside is better than what's on TV, but with the fighters moving, turning, etc., he still seems to see everything. He knows what he's talking about and it's obvious he's still exicted to be around the action.
That said, I hate the post-fight interviews in the ring. Hate them. It's the wrong time to be talking to the loser... give them a chance to come to terms as to what happened. And to the winner it's too often "What did you expect?" or "How does it feel?" type questions. Let the winner savour the moment. Let them breath deep and hear the audience and hear their own heart. Ask your questions later... we can wait for the answers.
