No one knows how much money Patriots coach Bill Belichick makes, for various reasons. First, the Patriots don’t want everyone to know the extent to which they’re blowing up the curve with Belichick’s salary package. Second, Belichick doesn’t want anyone to know his business, ever. Third, Belichick’s agent is surely under strict orders not to run his mouth about Belichick’s pay, even if it could help the agent attract other clients.
Against a reality of super-secrecy, the belief as of a year or two ago was that Belichick is making roughly $12.5 million per year. If that’s what he’s getting, he’s underpaid, by at least 50 percent.
