The roster shows 13 players, none listed as goalie.  In the previous year, there were 18 players, including one goalie (a Junior).
Go back two years, there were 23 players, including two goalies.

All 13 would have to be pretty good athletes. An athlete can block shots...just sayin...not that I would want to do it.

knowing little to nothing about field hockey it might be a tactical decision to have 3 subs instead of just 2 for the 10 field players
