Statisticians say that Bill Belichick made the right call against the Colts on 4th down
The fact is that the game was not won or lost on that single call. The problem was that there were key turnovers by the Patriots in the 4th quarter, and they couldn't stop the Colts' offense. That's what people should be focusing on.
That, and of course the fact that Belichick made the wrong call.
