Maybe we should give Ty Lue more credit. He took a team of Lebron, Kyrie, TT, JR, Shumpert, Kevin Love and others and got them focused enough to actually win a Championship. Each of those guys have some amazing basketball skills, but they also have some amazing Yang to go along with their Ying. Seems like we're seeing the "Yang" sides of just about all of them this year.
As for a coach, I'd love Walton, Messina or even David Blatt again. Bring a guy in that coach these guys up and build a cohesive unit from the start.
