Only CFB has this obsession that the best team must be the champion at the end.
Sure, the regular season "matters more", but at the cost of being completely predictable. Bama, Clemson, OSU, Oklahoma. 2 of the 4 at least will be there every year, so how does that make the regular season mean more again?
CBB has the format exactly right. Regular season is still important. Conference championship means more (aka Bama can't lose to Auburn on purpose to get a bye any more). Doesn't have to be 64 teams but should be at least 16. The team that wins the championship is the team that puts the best 3-4 games together when it matters most. If you are concerned about the best teams taking games off, work it to where there are four byes or double byes.
