i think i view tie as a way players not very much wanting to play.
though it lacks aggressiveness still they play, now i think it affects the overall behavior of your players. if they arent eager to really want to put more points tendency is they will just shoot more outside than driving in the lane and has tendency to get foulf or even injured.
your strategy of 2-3 is correct and i wont argue, but sometimes have faith in your big man! try to look at your opponents strenghts, at times i would set a defense of 3-2 even though surely he will play an inside oriented attack.
my intuition or strategy was to hold his guards, look at the stat sheet of his team. even if they play inside and you see the pg or sg is the second and third leading scorer and for example and his pf is the leading but his center or backup big men happens to fall to the 6to 8 place in points per game im going to gamble on shutting down his support and even his big man dominates the game by law of average he will miss shots , yes he will rebound but you have to worry only is the center gets a good game and probably .. . . backup would just play a few minutes because their starters needs to work a lot on this game.
