Baltimore Ravens quarterback Joe Flacco is great. The problem, however, is he doesn’t always play like it. Let’s face it Ravens fans, Flacco is inconsistent in his play. When he’s at his best, he goes on historic runs in the playoffs that rival the greatest quarterback to ever play the game. When he’s at his worst, he’s no better than a mid-round depth quarterback struggling to stay alive.

If Baltimore wants to see another Super Bowl, they need to figure out which version is the right one and how to see more of his best on the field.

One season removed from an ACL tear, the first true injury of Flacco’s career and he had arguably one of the worst seasons of his career. Sure, he finally got over the 4,000 yard mark that so many wanted to belittle him for. But it came with 20 touchdowns and 15 interceptions, helping doom a struggling, young offense and holding back the whole team from the postseason.

Despite his calm demeanor, Flacco had four multiple-interception games in 2016 and only 3 games without a turnover. That sure seems like a guy that has his bad plays pile up if you ask me. While he may not show it emotionally, we’ve all seen Flacco get a little restless in the pocket when he’s taken some shots and things aren’t going his way.

When Flacco performs his best, it’s with a quality offensive line keeping him upright and a running game that takes the pressure off. Forget his weapons, he’s made do with far less than he has right this instant thanks to his cannon of an arm that can force the ball into places it probably should be in the first place. It seems that with a line and running back to alleviate that pressure, Flacco doesn’t force passes as often and doesn’t double down on his mistakes.

One of Flacco’s best seasons was 2014 where he threw for 27 touchdowns and only 12 interceptions for a rating of 91.0. In that season, Flacco only had three multiple-interception games and finished with seven games without a turnover at all. That also includes a game where Flacco torched the Tampa Bay Buccaneers for five touchdown passes in one half, adding a field goal drive to make it six scores total in the first half.

In that season, Flacco had an offensive line anchored with their new left tackle Eugene Monroe after a trade with the Jacksonville Jaguars. He also had a new running back in journeyman Justin Forsett, who blocked as well as he ran the ball. It all created a perfect storm for Flacco where he had time and options on every play and a play-action that could fool the best defenders in the league.

Of course, we can look back to the Ravens’ Super Bowl run for a repeat in the pattern. Flacco threw 11 touchdowns without a single interceptions, tying Hall of Fame quarterback Joe Montana for the best postseason run ever. Flacco looked as confident and poised as I’ve ever seen him in a game, much less multiple games. Once again, the pattern emerges of a rushing attack that gashed defenses for big yards and wore them down over four quarters along with an offensive line that stepped up in a major way to keep Flacco happy and healthy.

So while it’s tempting to call for wide receivers to get added to the team, it’s really making Flacco comfortable on the field that gets the greatest success. If Baltimore wants to see more of that and have the real Joe Flacco stand up once again, they have to invest heavily in their offensive line and backfield.
