I don't think we could actually catch refs fixing games. Its possible but unlikely. But a private investigator can find lots of other things. I think some refs have intergrity and others lack it, and those that lack integrity are more likely the ones following Goodell's unspoken grudge against us from bountygate, and their own ref grudge against us from the no call, and being biased against us. The key it to pressure or remove the refs that lack integrity, and to do that we don't need to catch them fixing games. We can catch them cheating on their wives. We can catch them drinking and driving. We can catch them doing meth. Anything is good that gets a morally questionable ref fired from the NFL, causes them to quit the NFL (wife says no more road trips after they are caught cheating, or divorce leads to a child custody fight where they can't tell the court they are gone every weekend half the year), or causes them to stop making so many bad calls against us for fear of being investigated in their personal lives. The idea is that if refs make our seasons difficult, we try to investigate them fixing games, but in the process we end up making their personal lives much more difficult. Goodell has a lot of power, he has billions, but he can't make a refs wife stay if we get pictures of the ref with a stripper on the road. If we force enough 'sinner' refs out of the league, we will get more 'saint' refs who have a strong sense of personal integrity in how they call games, and the rest of the sinner refs may back off in order to sin in private. The point is not to influence the league, its to influence the refs directly to call a fair game or have their personal life under a lens.
