They need to manage Robert Williams, they aren't winning the championship without him. The defense has been elite in 4 of the 5 games he's played since coming back.
I actually like the idea of a mid-season tournament, the regular season has been ruined for contenders since the Warriors broke the regular season wins record and lost in the finals, a shake up isn't a bad thing. Don't think the pool play is the best way to do it though. I would make it a East-West 2-15 Bracket with the 1 seed getting a first round bye and instead of cities bidding on who gets to host the all-star game it becomes who gets the final four. Also if a team not a top 4 seed wins it, they become the 4th seed and have homecourt advantage for the first round of the playoffs. Incentivize players and owners to want to win it.
