Bottom line, Gatas NEEDS more players if they want the team to continue playing, be it this season or next season. If they were to field the team only with the members they have now, they'd have some of the girls (like Nono, for example), being forced to play entire games, with their only breaks being time-outs and halftime. Combine THAT along with their schedules as H!P members, and physically the girls will soon just collapse out of sheer exhaustion.
IMO, they need a second goalie and AT LEAST 4-6 more field players. Remember that since they began playing as a team, all they've done is lose players. To my knowledge, this is the FIRST time that they're acutally looking to add new team members.
