I think Preds, 3Dtristate Warriors are the only tryouts still to come. ExpressNorth got a lot unhappy 91TS boys with the lure of AA and A teams.Schrieber got greedy seeing the numbers at their tryouts hence multiple teams, can't imagine anyone being happy at the end of next summer.
All the programs in Westchester are getting stronger each year. PrimeTime being the most competitive. Warriors have the Savastano's coaching so given time developing, their younger teams will be strong by HS. 2Way plays in B/C level tourneys but as they get stronger I'm sure you'll start seeing them in the more competive tournaments. 91TS has to up their program to attract better talent or they will always be a catch all for the kids not making any other team.
