I think you're confused by what a play-by-play guy is vs a color commentator. Color commentators are typically the former athletes, like Chael. Their job is to add insight and analysis to the action. Play-by-play is a completely different job, and is NEVER done by former athletes, in any sport. Their job is to host, ask questions of the analysts, read scripted adds/info, and call the action as they see it. Anik is great at this job. Someone like Chael would be completely lost and wasted as a play-by-play guy. He is decent as a color commentator though, but like I said, its a completely different job.
