Advantages:
Owners
1. Able to duplicate MLB
2. 2 less teams. odds of making playoffs increase. There was no mention of eliminating 3 wild card teams,or following MLB playoff format.
3. Potential to fill leagues faster with less wait time after rollover, It may not be a significant advantage, but it is obviously easier to fill a 30 league team than a 32.
WIS
1. Potential for leagues to begin more quickly. 1 extra season every year or so would mean increased revenue.
2. 2 less 4th place credits.
BTW. I do agree with the 2nd round 4/7, but that has nothing to do with this topic.
