Yes, i played with my backup guards, maybe your theory is good, and maybe you're right. But still, my PG/SG/SF had some OD's (Not good at all, only 6 or 7 level defense), and they all could pass the ball, PG and SG had passing lvl7, and SF - lvl 5 passing skill. I thought it will be enough, but, how we saw, it wasn't :)
Anyway, thanks for your time. :)
