I think you have to press all out all game. Hope you have the depth to do it. Run every chance you get, made baskets too.
On offense, spread the floor as wide as possible. Vacate the post area much of the time. Set screens away from the ball, but not ball screens, they hedge and recover too well. So, try to create one-on-ones, try to prevent the help defender from getting there, and drive, drive, drive. Kick out to shooters if they do help. Go small so you have 3-4 good options.
That is, if you have the personnel to do all that. Need to score 70 points.
