It benefits the weaker (for lack of a better word) teams in the ESCC big time. They will be be in divisions now where they can face more teams on their level. They didn't have as many options in the ESCC.
It will kind of hurt Mount Carmel in 2019 because 2 years ago when they scheduled Maine South to a home/away deal, it was to add a competitive game on their schedule when they, unfortunately at the time, agreed to go to the Green Conference for two seasons. Now they have an away game with MS and add Marist, BR, and Montini to their schedule with LA.... Brutal....But I welcome it 100%. Last year after the MS and LA game it was a snooze fest of a season that included the PC forfeit. It didn't start getting fun again until the second round of the playoffs against Lake Z.
