Owner Mikhail Prokhorov is happy with the progress of his team — he was on hand in Brooklyn to witness the opening two games of the Nets’ first playoff series since 2007.

But in an interview with Bloomberg Television last week, Prokhorov admitted that there’s still some work to do if they want to reach his ultimate goal: a championship.

When Prokhorov purchased the Nets in 2010, he guaranteed the team would win a title by 2015. So what’s missing? Two things.

"One more good player," Prokhorov said in the interview. "And we need time to make a really strong team."

Nets interim coach P.J. Carlesimo was asked of Prokhorov’s assessment before Monday night’s Game 2 against the Bulls at Barclays Center. He handled the matter deftly.

"That’s a loaded question," Carlesimo said, smiling. "You think I would disagree with Mr. Prokhorov? I think that’s an astute statement. Having said that, I love the 15 players that we have now."

One thing’s for sure: getting one more piece will not be easy. The Nets have no cap space and few tradable assets.
