you really want to focus on the spd/per combo for back court scoring. if you've got tons of those two, you can have a great scorer, with **** everywhere else. ball handling is also fairly important, and you can also have lp oriented guards, for whom lp and ath are decently important. really, lp is valuable for a per type guard as well, but the value of ath only really kicks in as lp gets more and more important, and still, spd is always significantly more important for a guard, on offense, than ath. to try to quantify that a bit, you almost can ignore ath for pure long range scorers, but for driving guards, you dont want to do that any more. also, ft% is pretty important for those lp type guards.
