These guys who think Brady is the only QB in history to modify the ball a little outside the rules doesn’t know the sport.
Alex smith talked about the chiefs this year use a baseball mud and coffee grounds to darken their ball and help it stick better. Watch their highlights and it’s clear their football is a few shades darker than their opponent. Doesn’t matter, it’s allowed under the rules. He mentioned he likes it less air when it’s cold weather and as much air as possible when it warm weather. It’s something every team does, Manning was the biggest support of Brady when this all went down among active QBs, because he was also doing it especially in Denver because of his hand grip issues, it’s why he went to the gloves once Brady got caught is because he knew the nfl would be checking more and he couldn’t have them underinflate them anymore.
