Rodgers is a top 10 QB of all-time and by the way he is 11-8 in the playoffs with a SB win. Only QB's off the top of my head that have been better are Brady, Montana, Unitas, Elway, and of course Peyton. Peyton was 14-13 in the playoffs, just above average but the difference is he has won 2 SB's which is huge.
Spygate's impact was before Spygate was revealed, IMO, that is why it goes back to those first 3 rings. Then articles about Doug Flutie, who was a backup Patriots QB hearing instructions from the sidelines well after the 15 second cutoff for QBs, were also released that created pause for a few folks. The fact that Charlie Weis and Brady, who was not nearly the QB he was now, then, being able to know what was coming from Blitzburgh D in 2001 and 2004. For Hines Ward to suggest the Patriots were calling their defensive plays before it happened, you can view it as sour grapes or believe there is some merit to it. As recently, the filming on the Bengals sidelines they were docked for which does not reflect well on the organization that was already caught for SpyGate. The hiring of a guy Ernie Adams, who had a photographic memory, hired by Belichick, to radio down signals based on their filming, there were articles about it too. He was not an OC or DC but had Belichick's ear. There was way too much smoke to not suspect fire. Whether you believe it or not, it is purely up to you.
We won't truly know because Goodell destroyed the tapes of the sideline filming when he was a fledgling commissioner and at that point, the integrity of the league was something he was trying to protect and later, over compensated with excessive punishment towards Patriots for Deflategate, IMO. So, unless Belichick or someone in their staff comes out and admits it, you will never see more proof of it. It has been hashed and re-hashed, so again, I don't wish to participate in too much back and forth on this front, people will believe what they want to believe. I will leave it at that.
But as far as Brady is concerned, what he has done so far reduces that impact, IMO, to cement himself as the GOAT. That is undeniable to me. First QB to come back from a 10 point deficit in 4th qtr. of SB, first QB come back from 25 points down in a SB, first guy to take a SB to OT and win it, first guy to take a team to a SB in their home team, enough said. The accolades are well deserved.
