http://hoopramblings.blogspot.com/2012/11/the-101-best-win-shares-per-48.html is the old list.
New list, Kevin Love at #101 (it sorts funny, trust me, Love is #101). http://bkref.com/tiny/yMZ2J
Notable -- 5 new entries in the top 20 (LeBron 1, Durant 2, Curry and CP3 1 each).
Youngest -- Shaq and then Anthony Davis. Oldest -- Karl Malone and Wilt.
Longest ago -- 4 guys in 1951-52
Latest -- 4 guys this year.
Year with the most -- several tied with 4 guys.
Huge drought -- from 1978 through 1985, only one guy had a WS/48 high enough to make the list -- Moses Malone in 1982-83. Weird, huh? Bird and Magic were young players, Dr. J was in the league, none of them played well enough to get on the list.
