Enjoyed watching him play and rated his (individual) play but would not call Rucker a "leader" by any stretch.
He was one of the pioneer, shoot first and second type of scoring point guards.
Played with some amazing lineups and never won anything. Also was 'limelight' as well as ball dominant where ever he went.
In his Youtube podcast series recorded on either a Nokia N95 or a potato - he doesn't exude that "mateship, relationships matter" vibe like say the D-Macs or the Darnell Mee, the pass first PGs that you do associate with leadership.
In his chat with Ricky Grace, who he cites as his main rival (probably accurate), you can sense for him it was always an individual matchup, not a team vs team one.
Post playing days - unlike again a D-Mac who worked the system to try and get coaching gigs, or Mee who went back home to coach, Rucker focused on individual coaching. Which pays more, is more "flexible" etc. That's just the vibe I get off the dude observing him over time.
Back to his playing days, I also didn't really see that leadership vibe of elevating the play of others around him - more playing for himself than anything team oriented.
Wouldn't be one of my top selections for a Head Coach, especially unproven or without any real effort to put the time in Assisting, NBL1 etc.
