Except that Rodgers says he likes to overflate footballs...and overinflating them actually would make it more difficult to catch -- especially in pelting rain conditions -- versus easier.
The issue is less what aided (or not) Brady's throwing...'twas more about what aided the Patriot receivers' catchability in such wet conditions.
Ask The Chargers about “catchability” since they were involved in using the banned substance “stickum” in 2012. Or ask The Seahawks about those 300k in fines they are paying this year for illegal practices.
This stuff goes on with every team.
