Well after some high-profile, highly-subjective calls in two big games against the SEC's front-runner teams (Florida and Alabama), and some corresponding criticism from the coaches who got the short end of the stick, it seems like the SEC is just going to lock things down for now.
This seems like a really desperate move - something a despotic ruler would do when his corruption is exposed: "Well, I'll just prohibit any criticism or free speech!"
Even if the criticism isn't legitimate, the SEC can take a much more transparent and proactive approach to this. Show folks how you're planning on addressing refereeing. At least make it seem like you're doing something, even if you're not.
Bringing the hammer down like this makes it seem like you're trying to just put a lid on the problem.
