Well, "grandstanding" is what that member saw it as. And no offense, but your current claims means as much as a twitter rumor unless you are providing us with proof.
The question was never can he AFFORD to buy the Kings and build and arena. Yes, he can if he wants to spend a big chunk of his money. The issue is the Maloofs are not selling. There goes the buying the team plan. For any committee looking at this, it doesn't matter if it Burkle or Slim, if there is no seller then there is no discussion.
Also regarding Burkle group's claim that the team can succeed in Sac, how would they know? The Maloofs never opened their books completely for them to see. Its just pure speculation. If its based on the fact that Burkle has deep pockets and doesn't mind losing money, I'm not sure the NBA would approve of a team staying in a city even knowing they are losing money. The point is there is no way for Burkle's group knows 100% the Kings can thrive financially in Sac and that they can build an arena. Its all speculations at a very late stage in the game.
