Rolling all the way to the right sideline, Flacco flung the ball deep downfield to hit wide receiver Chris Moore on the left side of the field.
Flacco estimated that the pass traveled 55 yards in the air.
"I don’t know if you usually have to throw a ball that far in game-time situations," Flacco said. "Yeah, when you’re out here trying to see how far you can throw the ball, then yes, you’re throwing the ball that far. It’s not very typical to have to throw the ball, really, more than 50 yards in a game."
Ravens quarterbacks coach James Urban recently said Flacco has one of the great arms in the history of the league.
So, how far can Flacco throw the ball?
"I don’t know. It kind of sounds like bragging," Flacco said with a smile. "I’m either lying or bragging, so I don’t know how I want to answer that."
But throwing the ball deep has been a struggle for Flacco recently. Over the past five seasons, he has connected on 48 passes that traveled at least 25 yards in the air. That ranks No. 17 in the NFL.
Last year, Flacco averaged 5.72 yards per completion, the worst of his career. It also was the second-worst average over the past five seasons. Only Derek Carr struggled more, averaging 5.46 yards per attempt in 2014.
The Ravens have high expectations for Flacco this year because he's not dealing with an injury in training camp for the first time since 2015. He also has new targets in Michael Crabtree, John Brown and Willie Snead.
"He has some weapons that he can use," cornerback Brandon Carr said. "The chemistry is better with this offense. I think his confidence is really out of the window right now."
