How far along into the season did the goalie quit? If player isn't coachable that's not good. You will get yelled at and need to suck it up. These kids are 14. There is a saying I saw "uncoachable kids become unemployable adults, let your kids get used to someone being hard on them." Why would someone flush such a great opportunity down the drain by quitting a great team like that is something they only know themselves.
The 2018 Terps are a good team beat HHH Dukes and battled 91 Extreme. So would say they are one of the top teams at this age group. I am sure MC will put together a great team for next year. |
