I did a quick count on Hotstat and saw that MPSC only had one team in Premier league this fall whereas Bridge had 5 (that includes the U14s). Although I haven't counted, it seems that MPSC is fielding far fewer challenge level teams as well. Especially on the girls side it seems like there are fewer options for an elite player to compete at the highest level at MPSC unless they bring 11 friends with them.
