Two things:
1. Some of you are misunderstanding this story -- it's not about some league edict to fix games; it's about a single official who got in too deep with gamblers and agreed to manipulate calls to affect the spread at the ends of games. For all we know, the official was pushing favorites out further late in games to ensure that the favorite would cover. Not trying in any way to excuse the conduct, but this is a far cry from the claim that some vast conspiracy has officials determining outcomes at the league's insistence.
2. I explained my reasoning in another thread, but given that this investigation has been going on for a year now, I'd be absolutely shocked if we're talking about a high-profile official who called crucial playoff games. I suspect, frankly, that we're dealing with one of the middle-level referees -- someone who's been in the league for at least 5-10 years, but someone who doesn't normally officiate significant games. I'd be shocked if it's a name that everyone immediately recognizes.
