The New York Times, in a discussion of the plausibility of Donaghy's claims, discusses the FBI's 2007 investigation of Dick Bavetta, who was the lead official in Game 6.

Bavetta's name has not come up much in the ensuing saga, so it's interesting to note the feds took such a keen interest in him. A legal expert in the Times story notes that the lack of charges against Bavetta (or any other ref) does not necessarily mean that the feds are not continuing to investigate the parties. These things take a lot of time.

There's one more quote I want to point out from this story:

How much stock can we put into these statements considering Donaghy fixed games under everyone's nose? No one seemed to suspect Donaghy, so why does it matter if they have never suspected Bavetta or any other ref?

I don't think I've linked to TrueHoop's absolute must-read interview with a professional NBA bettor yet. Lots to chew on there.
