I think the WCS stuff is a smoke screen from either the Larry Legend or the WCS camp.
Larry had a good draft record as a GM.
The smallball stuff with George is exaggerated. It's only partially true. As long as LeBron is a perennial finals participant, having one of the handful of wing defender who can challenge LeBron as much as possible basically means you can/must have that smallball lineup with 1 Center and PG/Leonard/Butler/Iggy/Draymond/... nominally at PF. Teams must practice that sporadically during the regular season
I also think Roy Hibbert lacks the "testicular fortitude" to test free agency after his weak 1 1/2 seasons a year before the cap explodes and he can easily secure himself a better long term contract in an environment where everybody but the Nets have tons of cap space.
So what could have happened here:
1) WCS camp hasn't received too much positive feedback from higher teams and fears he might drop to Indiana at 11, who have Roy Hibbert. That interview helped him out there and he wants to win back interest with other teams.
2) The Pacers want something done about their roster and sent word out through WCS that they are open for trades around Hibbert.(Hibbert has PO, and such a move might get a team to the table that wants him. So you work out a handshake deal with a team over the cap. Hibbert opts in, getts traded, Pacers get Trillie. Prolly 3 way shenanigans needed or seperate trades)
3) The pacers want Willie, but couldn't agree with his camp on him sitting out other interviews/workouts etc. Now he leverages that feedback.
I personally think that WCS is interesting. But none you'd die for, except if he becomes DeAndre Jordan with the brain of Tyson Chandler. And I think that's a long shot. I don't think he's that explosive and smooth.
