LOL, a guy who can't spell is criticizing me for my reading comprehension...
But re-reading your statement underscores the point that Brady could not prevent another great QB in his conference from winning a Super Bowl other than maybe Phillip Rivers. At least Mahomes has stopped Allen, Lamar and Burrow from ever getting a ring (to date). As you said, Roethlisberger and Peyton got their rings. On that list, the Broncos were the best and Brady choked against them.
You see, that is what makes Michael Jordan who he was. He blocked greats like Ewing, Stockton, Barkley, Malone, and others from winning championships. Brady is simply not in that class.
