22 in your division (too much? That's what they did in the 154 game / 8 team years)
6 against the other divisions in your league
6 against another division in the other league
OR
16 in your own division
6 against the other divisions in your league
6 against another division in the other league
6 against the teams in the same position as you in each division of the other league.
I get to see teams in the other league at the minimum of once every 4 years instead of the current 6.
I would mandate that you play 2 series (H & A) against every team in your division to open and close the season.
The interleague season is split into June and August with the intraleague season filling in the other times (along with the extra intradivisional series).
Playoffs - seed divisional winners 1 - 4. 1 plays 4, 2 plays 3. Home field for WS is determined by which league won the more interleague games.
Never happen.
