Let's pause for a minute and congratulate me on the fact I actually know the names of two teams and what they were playing for. I'm as surprised as you are.
The reason under inflated balls (I'll never get tired of that phrase) make a difference is that they're easier to grip and throw.
Here's the thing: while the issue of under inflated balls is a relatively new discussion for the NFL, it's been rampant in ad agencies ever since the very first "new and improved." Many have suffered the affliction for years. Surprisingly, the condition is anatomically agnostic. It affects both men and women in the business.
The symptoms are readily apparent, although they do vary. They can run anywhere from letting the client write the copy, to telling the creative team, "I could present this but I know you can do better." Other symptoms include run-on meetings, not challenging client mandates, letting the work go down in flames without so much as a whimper, insisting the bulk of the budget be shifted to digital and reading the brief word for word.
If you find yourself in a completely ridiculous argument lasting four hours or more with someone who has never created a thing in their life, yet continues to criticize your work, they most likely have an untreated case of under inflated balls.
Try to be understanding and not judgmental. Give them the same reassuring, constructive advice their doctor would.
Grow a pair.
