i think it will cost a lot of rebounds, but even when he has superior rebounding he would get more then 50% of the misses Shots ;)
But i would play 1-3-1 only if you are sure your opponent playing with outside focus, or if he has the much better team and you need to hit its tactic perfekt to compete. normally the 3-2 Zone was better, because you aren't messed up when your opponent plays normal and even against look inside you could have some luck.
