I don't think Princeton is the answer. Even when I play guard/SF types in PF with princeton, they still take useless shots and I lose 90-60.
If any team will work with base offense it's mine, my guards are basically 15s in every offensive skill except JR (JS, DV, IS). So I might train some JR this season

I dunno about buying different bigs, right now I just have TL filler junkers on the cheap.
