I read it again just so I didn't miss anything. Again, what the kid proved was that Brady could have benefited from the deflation of the footballs. This has also been the contention of former NFL QBs Warren Moon and Troy Aikman. The act of cheating is intentionally skirting the rules of the game.
My previous post that said everyone knows he cheated was based on all the circumstantial evidence that he conspired with his bro, otherwise know as "the deflator," to doctor the football's against NFL rules. Text messages and a video of deflator dude going into a room with a bag of footballs. Brady throws a pick to the Colts defensive back and said player immediately knows the football feels funny. Like someone took a needle to it and drained the air out of it.
That would be cheating.
There's enough evidence that any reasonable person would determine that there was some shenanigans going on with those footballs.
The kid didn't prove he cheated. Proving he cheated would be like having some videotape of Brady's partner in crime deflating the football's in the closet.
Regardless, it's a good story from a kid that hates Brady. Haters gunna hate.
