Are actually giving newcomers advice to keep playing just one tactic. My god.
Whoever is reading this and just started please feel free to test out strategies and you can not win every game fielding 4 Centers and a PG + playing inside.
I did exactly what Crazy said and was successful with it: R&G as unique offensive tactics. The rationale is quite obvious for beginner to do so - well rounded inside players are very expensive, however if they flawed, prices drop dramatically. So I renounce on inside shot skills and focus in the acquisition on rebounders and defenders.
With this simple approach starting in season 7 in league 4, I play now second league and it looks like I am relatively competitive. (though have to say that try to shape my team now to become more flexible in offensive tactics). Basically, I believe that without focus on the outside tactics I could have only afforded a much weaker team and probably would have had less success.
