The problem is that half of the teams simply don't make the playoffs, and right now there are teams that go three weeks without a competitive game. That really shouldn't be longer, and teams that play BB more casually shouldn't be forced to play it less casually during the playoffs; that's not fair to them either.
I saw a post by Brian James a while back about starting with enthusiasm 10 and trying to maintain it (only using CT when required) which to me seemed much more logical.
I'm open to suggestions on that. It seems like in a three-game series, there's enough room for enough possibilities that having both options adds a more interesting gameplay element.
