According to Brett Favre's Book , The Vikings were also running a bounty program.

I remember reading (probably here), I'm paraphrasing

Sniff Test

BOUNTYGATE: intentionally injuring offensive players

Benefit: makes it harder on offense to drive and score and easier for you to win

Proof: Saints near bottom of league in injuring players

DEFLATEGATE: intentionally lowering air pressure in football

Benefit: Ball is easier to throw, catch and hold on to

Proof: patriots had fewest fumbles in the league, by a wide margin
