This is an excample of an allstar that are not even close to reaching the soft cap, and not the best weighted player.
This is an example of a SG that did reach his soft cap...

The only thing I would have liked is probably 2 or 3 pops in IS and passing (which if I had patience before switching to talls I could probably get). Other than that, this is an allstar player that is pretty much the backbone of my team. I believe potential is relivant to the player you wish to create. There is no point in wanting a hall of famer with the intent of training to a $30k salary.
