Personally when I evaluate a player, I figure everything out based upon what he is going to be when he is maxed out. For a good point guard, I try to have their ath and speed be around 120 when added together. Depending on your defensive it is different but I like to aim for around a 50 defensive. With passing and bh, anywhere above 70 is solid. If your point guard is fast enough and has good enough skills, he solid scorer even with a low perimeter. However if you want him to be more of a threat from outside then add in a higher perimeter. I'm sure other people will have different numbers but this is what I try to use. Granted I haven't been as successful as other coaches so take it for what its worth!
