Well, yeah... if you take off the 3 Super Bowl wins, it's not quite as impressive. I don't have a counterpoint to that.
Then again, you said that his post-Spygate career wasn't that impressive. Which is utterly ridiculous.
So, here's my challenge to you about "Deflategate"... with as much specificity as possible, tell me what Brady did to violate league rules and gain an advantage with the footballs.
Re deflategate -
1 - guy is known as "the deflater" on texts
2 - pats claim that nickname refers to his weight loss
3 - that same guy is on text discussing how he did not properly follow toms request during a jets game where balls felt like bricks
4 - that same guy is caught on tape taking the balls POST REF INSPECTION and taking them into a locked bathroom on way to firld (illegal procedurally)
5 - that same guy is on text receiving payment from brady in the form of autographed memorabilia
6 - some, not all, of the balls are measured to be below what would be explained by ideal gas law alone (tho i admit nfl procedures during investigation were bad)
7 - brady then calls this guy 7 times in a panic after story breakd
8 - brady destroys his cell phone and claims it is routine
Even without the measurements there is a mountain of circumstancial evidence that this guy was on bradys payroll and orders to illegally deflate footballs after being inspected by refs and placed in refs locker.
