I'll give Clifford two years. This is far and away the best roster he will have had in Charlotte and he managed to get those other teams to the playoffs, albeit in a weaker Eastern Conference.
If he doesn't Hurney (hernia?) and make the same mistakes he made his last turn, the Hornets could be a second round playoff team. I'll be interested to see what a few other guys do in Summer League (Williams and Liangelo Ball). I'd say the Hornets are nabbing a solid sharp shooter away from being solid. Perhaps Curry will want to come to Charlotte for two years to end his career and can provide that pick and roll with Ball.
Side note, how sick would the Hornets be to watch with Ball and Curry?
