Per the link:
"Each season will open with a pre-season Jamboree and teams will play on six fixed game days with one weather make-up date, all dates set in advance" So if there are only six fixed game days, and they are eliminating the double headers and just having 90 minute games, there will only be 6 games. Besides the pre-season Jamboree.

Another thing I don't understand is "Each player is guaranteed a minimum of 25 minutes of uninterrupted playing time each week" How does that work?
