As you (I think) previously stated... 5 figure fine up to a one year suspension...
The first is probably much more proportionate to the offense (if one was committed)
The second (I really can't see happening) if Goodell gets a hard on for his blatant disrespect for league rules
According to Goodell, he had considered suspending Belichick for the spygate thing, but felt a max fine and loss of a 1st round draft pick had a longer lasting therefore more effective punishment than a suspension...
I do concede that IF recent reports are found to be in violation of league rules, this violation does not seem to be near as big of a deal as spygate, but a rule is a rule, lol
