To me they're still relevant by the fact that they still get into the playoff. I mean, if you're an 8-4 team that manages to win their conference championship, they make it into the playoff, even though they really aren't that good. It's like in the NCAA basketball tournament, conference championships matter a ton for mid-major conferences, because not winning the conference means you likely don't even make the NCAA tourney. Besides, winning your conference is a heck of an accomplishment on its own.
