I've seen people posting only taking in account only the guard skills but as we are talking about the best PG i would add some inside skills as for me the best PG should have at least a triple-double a season if not more.
I'm training a PG right now but because of his superstar potential i don't see the relevance of his guard skills in this thread but as far as his inside skills i managed to get him to IS:10, ID:11 and Reb:9.
As far as guard skills in would go for JS:15-16, JR:12-13, OD:17, Handling and Driving 15-16 and Passing 17.
I like all-around players more than one offence oriented guys.
