Once Brady and Bellichick leave, I suspect Patriots’ games will have a lot of empty seats, they still are behind the Sox, Celtics, and maybe even the Bruins, in the Boston sports hierarchy.
Two points:
The latest rumor on Boston Sports Radio is that Bellichick is leaving at the end of this season to go to Cleveland. That he really was trying to draft Baker Mayfield at the beginning of this season and did not want to keep Jimmy G.
The Patriots Monday night football game against the Bills had a higher Boston area TV audience than all but ONE of the World Series Red Sox games. So, I am not sure I agree with your hierarchy designation. I would rank in audience support Pats, Sox, Celtics, Bruins, Revolution(soccer , Ha Ha).
