Suspected NBA Referee's Games Hit the Over More Often: Over the last two NBA seasons, games refereed by Tim Donaghy scored more points than Las Vegas expected 57 percent of the time (79 of 138 games), according to R.J. Bell of the sports betting site PreGame.Com. In the two years prior, his games hit the over 44 percent of the time. "There is an absolute correlation between the number of fouls a referee calls in an NBA game and the number of points scored by the teams," he writes. "An NBA ref who intended to illicitly influence a game would do so by calling more fouls, and thus his games would be higher scoring than average." A source told the Denver Post Sunday that the league has known about the FBI's investigation of the referee since January, rather than after the NBA Finals as reported elsewhere.
