That's not what I asked you.
Look, I agree completely that the champion of a given league is not always the best team when that champion is determined by a playoff tournament. But that's true of
any tournament, whether it's 2 teams or 68 teams, as the best team does not always win every game or series. (Among those 4 MLB teams, one of them was, by definition, the best team in the league over 162 games.) So if you're going to have any playoff format at all, you're conceding that the best team in the country may not become national champions.
But there are really only two ways to determine the best team: have everyone play everyone else (as with most soccer leagues) and give the trophy to the team on top of the table, or have a bunch of experts get in a room together and announce the best team. FBS college football is the only sport I know of that embraced that second option, and most years that led to people screaming that the experts had chosen the wrong team. And that's why I like the playoff: we can still argue about who was the
best team in college football in 2024, but there will be no argument about who won the national championship.
