Nope didn’t say that. First of all. The NFL hasn’t said they cheated only that the 11 of 12 balls were under inflated. The cause has yet to be determined. If the NFL comes out and says they cheated then they cheated. Until then, it’s all speculation and hearsay on the cause.
If the Colts player could tell the ball was under inflated, why didn’t Brady notice that. Tom Brady is the quarterback, and the most expert about noticing the inflation size of the ball.
My only guess is that he knew about the cheating, or noticed that the ball was under inflated, and did not report it.
Either way, it appears to me that Brady is also a cheater.
