multiple dirty refs in the NBA and not just Tim Donaghy, then the NBA would have been finished, it proves Donaghy was correct, and we may take into consideration some of his other claims, like:

On June 10, 2008, Donaghy's attorney filed a court document alleging, among other things, that Game 6 of the 2002 Western Conference Finals between the Los Angeles Lakers and Sacramento Kings had been fixed by two referees. The letter states that Donaghy "learned from Referee A that Referees A and F wanted to extend the series to seven games. Tim knew Referees A and F to be 'company men', always acting in the interest of the NBA, and that night, it was in the NBA's interest to add another game to the series." The Lakers won Game 6, attempting 18 more free throws than the Kings in the fourth quarter and went on to win the 2002 NBA Finals."

And seeing that the NBA still employs those refs, they could still be extending playoff series.
