Tom Brady
When you hold a title like "Greatest of All-Time," you are bound to have plenty of people hate you. Tom Brady certainly fits that mold, and Steelers fans will forever hate the guy.
It isn't even necessarily because Brady did anything wrong toward the Steelers. It is the simple fact that Brady has had so much success against Pittsburgh over the years. In 15 games against Pittsburgh, while with the Patriots, Brady went 12-3 including the postseason.
Brady has played the Steelers three times in the AFC Championship Game, and he's won all of them. Not only have the Steelers never beaten Brady in the Championship Game, but they've never beaten him in the postseason, period.
Brady owns the Steelers in the postseason, and that's painful to admit.
If we're looking at the regular season, overall, Brady has thrown for just under 4,000 yards, 30 touchdowns, and only five interceptions in 13 regular season games against the Steelers. He also owns a career passer rating of 109.2 against Pittsburgh in the regular season.
Again, Brady is the greatest to ever do it. But, Steelers fans can't help but hate the guy.
