When Nets general manager Billy King alerted owner Mikhail Prokhorov the team could potentially get both Paul Pierce and Kevin Garnett in a trade with the Celtics, Prokhorov’s response was swift. “Hell yes,” Prokhorov said with a smile in an interview with the YES Network that aired at halftime of the Nets’ 101-100 victory over the Heat in Brooklyn on Friday night. In acquiring the two future Hall of Famers — along with Jason Terry — from Boston, the Nets ensured they would be in line to pay a heavy luxury tax this season. Their current salary commitments, including both payroll and luxury tax payments, are set to be about $189 million, far more than any other NBA team, after the moves they made this summer. But Prokhorov said paying such a heavy price for a shot at a championship team was an easy decision. “I don’t go halfway on anything,” he said. “I always go all the way.” Prokhorov also said he had no problem with the NBA’s investigation into the signing of fellow Russian Andrei Kirilenko this summer. After the Nets landed Kirilenko on a one-year deal for the mini mid-level exception of $3.2 million that included a player option for a second season, teams around the league cried foul. But the league looked into the deal and found no wrongdoing on the Nets’ part.
