The Team 91 2029s is almost a whole new team. Yes Preds 2029 is mostly the Team 91 from last year.
I am FCA 2029 dad. Our team is almost half Crabs kids, another half is the 29/30 FCA from last year and a couple others mixed in so it is very new. This weekend at Maryland Lacrosse Fall Tournament was their first games together. We did not even have a scrimmage before Madlax Capital got a chance to unload on us in the first game. Considering the second game was Bethesda Blue that was 5-2, it seems very good for the 2029 FCA moving forward. But only time will tell.
Tier 0 would be Annapolis Hawks by a long shot. Everybody starts a tier below them. |
