it was anti bb because he embarrassed their home team, the jets, by refusing to coach them then came to their most hated rival...a boston team and won.
as far as underinflated footballs they were hoping to get bb there as well to get him out of the league. unfortunately for them bb has nothing to do with football prep. as we found out every qb has always done football prep to their liking. my opinion but tommy just got caught up in the bb hate. that's why the league came out with 2lbs under pressure not .2 and never changed it. again just one fans 50,000 foot view.
