Whether or not you believe that the deflated balls used by the New England Patriots in the AFC Championship Game is worth punishment or not relies on two factors: whether you have a passionate feeling (positive or negative) about the team and whether you believe in following rules strictly. Neither of these should have as much impact on the final resolution as one other major factor.
Personally, I’m a fan of the team and specifically of Tom Brady. He has to be in the discussion as a top 3 quarterback of all time based upon his longevity of success; this would be his 4th Super Bowl victory out of 6 appearances spread across 14 years if they win. I’m not a fan of Bill Belichick for the same reason that they should be punished for their actions.
