Wings: I am leaning toward a forward right now . . .
Defensive stalwarts: Ben Wallace, Dennis Rodman, Larry Nance, Bobby Jones, Shawn Marion (should add Horace Grant and Rasheed Wallace here too . . . )
Comparing 4 guys known as scoring 3's: Carmelo Anthony, Billy Cunningham, Marques Johnson, James Worthy (should get around to adding Chris Mullin and Glen Rice to the mix, maybe even Jamaal Wilkes or Bobby Dandridge).
Best bigs left: My favorite is Mel Daniels with his 2 ABA MVPs and 3 rings (2 as clearly the best player) -- played like Alonzo Mourning offensively and Moses defensively -- but his weaknesses (and the weakness of the early ABA) are problematic. Bill Walton and Connie Hawkins are super short, super peak guys. Neil Johnston, Amare, Dan Issel, Jerry Lucas, and Spencer Haywood have offensive creds but bigs who don't play good defense are problematic for me. Even Zelmo Beaty, Elton Brand, Chris Bosh, Chris Webber, and Yao Ming are on my radar.
Jerry Lucas, Mel Daniels, Bobby Jones, and Shawn Marion are the main guys on my list right now. Lucas was a great rebounder, outstanding secondary scorer with stretch the floor range and good passing skills. Not a good defender though willing; did a good job post prime taking over for injured Willis Reed and playing most of the center minutes on the Knicks second title team. Daniels is a 2 time ABA MVP; I'd take him over the flashier numbers of Neil Johnston and the 50s bigs because even though the early ABA isn't strong, it was better than the 50s NBA, super warrior type, short career arc. Jones is a great glue guy who gave up minutes and starting roles to help his team, still is the all-time record holder with the most 1st team All-Def awards, very efficient high energy, good passing, nice midrange . . . was the best player on the best team in 1975 ABA without great help (Denver had a better record than either Erving's Nets or Gilmore's Colonels) who made Larry Brown's jump and switch defense into a winner, limited minutes player is his main weakness (and not a good rebounder for a 4). Marion has a long career as one of the great offball slashers and wing rebounders of all time, versatile, was clearly the second best player (better than Amare who got all the awards) on those Nash led Sun teams -- Suns didn't miss a beat when Amare went down; and did a great job on LeBron in Dallas's title run.
I guess I will tentatively vote for Bobby Jones for his versatility, willingness to sacrifice glory for team, and just being the epitome of what basketball should be about. If it's about winning rather than stats, Jones is your poster boy.
