mind you I have hardly any experience but It sounds as though finding a couple tactics that work well with your team or the team you'd like to be and then building in that direction sounds like a good place to start. You may also want to just jot down a couple things that you want in your team specifically like well rounded bigs or all players being solid inside and outside defenders. Then work to make that happen cause that tends to be what makes managers the most happy/satisfied (seeing theirs ideas and dreams create success and a winning formula). Also, I've learned that there are a million ways to be successful in this game, all it takes is the drive and passion to make your requisites into strengths.
We have a lot of great outside shooters. Unfortunately, we play all our games indoors.
