I'm not okay with them staying in mediocrity, but I also don't think that a Sixers-style Process is the only or best way to get out of mediocrity. The four most successful franchises of the last 20 years in terms of championships - Spurs, Warriors, Heat, and Lakers - had nothing near the Process to gain their success. There is definitely some luck and good timing involved in their strategies, but the overwhelming reasons for their success were simply good talent evaluation, roster composition, and coaching.
The Heat won because Shaq got pissed at Kobe and Lebron decided to play with Dwade. Charlotte isn't a destination city.
The Spurs and Warriors basically created their teams through the draft. The Spurs got the #1 pick and then mined Parker and Ginobili. The Warriors got Steph, Klay and Draymond through the draft. The Hornets have never shown the ability to draft.
The Lakers got the Hornets to trade them Kobe. Nice move...then got Shaq to come to the team. Charlotte doesn't entice top players to go there.
All of those teams go back to competent ownership and excellence in the front office. The Hornets have neither. Without blowing up the team, the best you can hope for is a string of luck. MJ is a bad owner/executive.
