What B teams look best this year since m&D red is an A team now?
M&D red is not an A team. They would not do well there. They will stay in B so the parents win and can say they are awesome without ever having to prove it.
I thought if you won the B division you were required to move up to A?
I believe this year NGLL A division will include Heros White, M&D Red, and MDU West. League suggested Integrity move up so as to not have 2 teams in the B division but they declined. While the 3 teams mentioned will likely struggles against the top teams in the A, 8th grade NGLL has enough teams that they will have some competitive games for sure.
Tournaments are a different situation. Tournament directors will not allow a club's B team in the top divisions (which is typically appropriate based on teams from other areas).
