Pittsburgh Steelers quarterback Ben Roethlisberger sure has looked like a shell of his former self over the team's opening three games of the season. But the future Hall of Famer did turn back the clock with one vintage passing touchdown in Week 4 against the Green Bay Packers.

Roethlisberger dialed up an astounding 45-yard passing touchdown to wide receiver Diontae Johnson over the early stages of the first quarter. The Packers secondary surely did not see this throw coming from the 39-year-old quarterback.

This was not just another passing touchdown for Roethlisberger, as it was the 400th such pass of his career. The Steelers passer became the eighth quarterback in NFL history to reach this historic milestone.

The list of quarterbacks who have thrown for 400+ passing touchdowns in NFL history is quite impressive, as it includes the likes of all-time leader Tom Brady (591) and Drew Brees (571).

This feat is among the more impressive ones of Roethlisberger's career. But for now, he sure is much focused on turning Pittsburgh's season around, especially as the team is just coming off of back-to-back defeats at home.

In the big picture, a key win over the Packers on the road could be a season-changing one for Pittsburgh at this stage in the campaign.
