Celtic CEO Wyc Grousbeck has joined other NBA owners in reporting a good first impression of Mikhail Prokhorov. In an interview, Grousbeck called Prokhorov "a people's billionaire...a regular guy with a whole bunch of money." Grousbeck said he was "favorably impressed" with Prokhorov during a meeting of the NBA Board of Governors. At least 23 of the NBA's 30 owners must approve Prohorov's bid.
