I almost forgot in my previous commissioner posts my best idea of all - what to do about the Division Series. A best of five gives fluky teams too much of a chance to win. Also, there is not enough disincentive to win the division and not just the wild card.
So here is my solution - have the wild card team play the team with the best record in the league (even if in same division) in the first round. To win the series, the team with the best record need win only three games, but the wild card team must win four. Hence, a best of six series, as the maximum number of games would be six.
The other series in each league, the one without the wild card team, could be either best of six or best of seven, I could be convinced either way.
