If you sort for a Win Shares over 130, WS/48 greater than .13 and PER greater than 15, then sort again for Guard or Guard/Forward, you get 9 guys in NBA history:
If you consider the 3 categories and give 9 points for a 1st Place finish, 8 for 2nd, 7 for 3rd, etc., you get the following results:
9th -- Ray Allen (5 points)
8th -- Gary Payton (6 points)
7th -- Clyde Drexler (7 points)
6th and 5th (tie)
Kobe Bryant and Jerry West (both 17)
3rd and 4th -- John Stockton and Oscar Robertson (18 points)
2nd -- Magic Johnson (20 points)
1st -- Michael Jordan (27 points -- he is #1 in every category).
Since every other player in the top 6 other than Jordan is a point guard (or combo guard), Kobe does hold a position of greatness by position -- it just appears that shooting guard is a really terrible position. Drexler and Allen are your next guys up, and a very good argument could be made that neither is a top 40 player. Dwyane Wade, injuries and inconsistency and all, may be top 3 shooting guard by the time he hangs them up.
Center -- Wilt, Kareem, Mikan, Russell, Shaq, David, Hakeem, Moses -- all top 50
PF -- Duncan, Malone, KG, Barkley, Petit, Dirk -- all top 50
SF -- LeBron, Bird, Durant, Baylor, Rick Barry, Dr. J. -- all top 50
PG -- Magic, Stockton, Oscar, West, Payton, Nash -- all top 50
Off guard is the absolute worst position of the 5 for all-time greatness.
SG - Jordan, Kobe, then..........Iverson? Clyde? Wade? Miller?
You should not have a position where after your top 2 guys you are struggling to put a guy into the top 50. All things being equal, it should be 10 off guards -- yeah, good luck with that.
