Before the Joe Flacco’s time with the Baltimore Ravens is up, he will win at least one more Super Bowl. That’s the opinion of head coach John Harbaugh, anyway.

“When he first walked into the building after we drafted him in 2008, [it was like], ‘Hey, dude, we’re going to win multiple Super Bowls. We’re going to win multiple championships here,'” Harbaugh said, per Jamison Hensley, ESPN. “And we’re going to.”

For the first part of Flacco’s career, this didn’t seem like such an outlandish prediction. Not only did the Ravens make the playoffs in each of Flacco’s first five seasons, but they always managed at least one playoff win. That run included three trips to the AFC Championship Game and of course, the Super Bowl XLVII win.

But since that championship, things have been rocky in Baltimore. The Ravens have only qualified for the playoffs once in the subsequent four years and have an overall record of 31-33.

From 2008-2012, Flacco completed 60.5 percent of his passes with 102 touchdowns, 56 interceptions, and an 86.3 passer rating.

Since 2012, he’s completed a higher percentage of his passes (62.5), but his 80-to-61 touchdown to interception ratio is worse, as his 82.5 passer rating.

That’s not to say that Flacco is the only reason for Baltimore’s sub-par performance over the last four seasons. But if Harbaugh is right and the Ravens are going to win at least one more Super Bowl, the performance of the quarterback will need to be a lot better.
