Former NBA referee Tim Donaghy gets 15 months in prison?

According to Newsday, "(Former NBA referee Tim) Donaghy, 41, pleaded guilty last year to taking cash payoffs and placing bets on games. The gambling scheme covered about 40 games in the 2006 and 2007 seasons and netted Donaghy up to $30,000 a year for game tips, prosecutors said." He was sentenced to 15 months in prison. That not much time for almost bringing down a league. According to the judge, Donaghy's sentence was also determined by his cooperation. Wonder if this is not the end of this story?
