Nothing but Nyets!

A day after getting the NBA’s blessing, Russian billionaire playboy Mikhail Prokhorov officially closed yesterday on a $200 million-plus deal to become majority owner of the New Jersey Nets, paving the way for their move to Brooklyn.

Following the sale, Prokhorov — a 6-foot-7 basketball nut and former amateur player who also happens to be the second-richest man in Russia — promised to deliver long-suffering Nets fans and new Brooklyn converts “a championship team.” He is the first non-North American to be a majority owner of an NBA club.

Under the deal with developer Bruce Ratner, Prokhorov’s Onexim Group is paying $200 million up front and an unspecified amount in the future to acquire an 80 percent stake in the Nets and a 45 percent share of the $800 million Barclays Center arena that’s the centerpiece of Ratner’s Atlantic Yards project.

He would also have the right to purchase up to 20 percent of the non-arena part of Ratner’s 22-acre development.

The Nets hope to be in their new arena, which broke ground this spring, by late 2012.
