The other teams in the "tier 1"top 3, ES and Heroes have a pretty liberal player rotation policy from what I can tell. Granted some play more than others but everyone sees the field at some point. Is it possible that Coppermine would have a even better team if had more equal playing time. Seeing the same players and scheme all the time probably benefits opponents. Good coaches can figure out a way to slow down something if its the only look they are getting especially as girls get older.
