To me, 70 is the key. If they get above that number, not sure we can win. Slow them down and they may get frustrated. Since they are very young, if we get ahead and get them frustrated, they are liable to press and make mistakes. They will play off of momentum swings, good or bad, so limit our scoring droughts and we will win. If they start playing with confidence, we will be in trouble.
If refs call 'ticks tack' fouls, that will also hurt us. Hopefully the game isn't dictated by a quick whistle.
