cause i didn't have good experience with all outside Attacks, my team is quite good at motion but i haven't good shooters to play Run and Gun. most likely there are teams outside who play good run and gun, and have trouble with motion my rival of the last season Flying Munchkins experience it like that. With Princeton i have even bigger problems, so the slowest outside offense isn't an option for my team.
Also i had problems in the past, with slower offenses against good team because especially in the beginning i got in enarly every attack trouble with the clock. So melk the time to make the difference small, is at least for me not the best approach.
I didn't say don't look at the opponent, and consider his strentgth or weaknesses, but i think you still had to look how your own strength match best against the opponent.
