This is spot on. There were countless times this bowl season where the color analysts for ESPN seemed to not know the rules/recent changes in rules for plays they were calling. Or I would spot something from their broadcast and immediately know what the review booth/refs were discussing, and the broadcasters were completely confused or took a few minutes to get on track.
The broadcasters have a tough job as it is, and the quick pace of games can easily cause confusion, which leaks into a downgrade in the broadcast quality. I would personally love to have a ref analyst on the call for each big game, instead of having one who gets brought in after questioned by the broadcaster, but of course that would cost the network more money, so that will never happen regularly. Also it is quite evident that the play-by-play announcers are more up-to-date with rule changes than color analysts. I think this is a training issue or a lack of professional approach from the color analysts, as it is clear that play-by-play announcers take their job much more seriously in their preparation for games. I think this is an industry-wide issue that crosses over sports.
