You will have to have the players to play a tactic effectively.
That's an excuse, in NT's you got the best players and 2-3 still doesn't work.
On the 2-3 game we played with a really good defensive SF, in the m2m game we just played a SG in the SF position.
As i said the only way to win this teams is to allow PF-C scores you, but defend good on the PG-SG-SF positionts in m2m.
And at the end the result is that it's better to defend m2m, but when the inside team sets a line up with serious OD and 3-2 it's really hard to score and win.
There's an imbalance between zones, ones work well others doesn't work.
