It's possible that the data there is more accurate than the blanket statement I made. However the article makes it clear that it is the rare 4th down and 2 when you are not better off going for it than punting. It's also possible that scoring is up since 2013 and the 28 is no longer the demarcation point. The more points that are scored the more valuable possession of the ball is and the wider the range of acceptable go's is.
Patriots are bypassing all analytics and establishing the run to score a TD, that’s tried and true strategy that works.
