Ravens quarterback Joe Flacco celebrated his 30th birthday in January.
Following his most successful season statistically -- a career-high 3,986 yards and 27 touchdown passes -- Flacco said recently he could envision himself playing another decade in the NFL into his 40s.
Flacco has started 112 consecutive games through seven NFL seasons.
"I don't feel any worse because of my age yet," Flacco said. "I think you learn more. I'm not going to be 50 and playing. I hope I'm 40, but 50, no."
Flacco is the Ravens' all-time leading passer with 25,531 yards and 148 touchdowns.
There are performance and financial components to whether a quarterback lasts into his 40s. Both Tom Brady, 37, and Drew Brees, 36, have said they plan to play that long. Previously, Brett Favre played at 40, as did former Ravens quarterback Vinny Testaverde. Peyton Manning is 39.
Flacco is entering what amounts to a contract year because of a $28.55 million salary-cap figure and $18 million base salary in 2016. Talks between his agent, Joe Linta, and Ravens senior vice president of football administration Pat Moriarty are expected to take place between now and the start of the free-agent signing period this year. Flacco's deal was always scheduled to be revisited after what amounted to a three-year, $62 million payout as part of his $120.6 million contract that included a $29 million signing bonus.
Flacco's focus is on getting acclimated to new offensive coordinator Marc Trestman and breaking in a new starting wide receiver and tight end with the departures of Torrey Smith and Owen Daniels in free agency. Flacco says he's continuing to make progress individually.
"I think the reason that it changes maybe a little bit is because you learn more each year," Flacco said. "I'm comfortable with what I do in the offseason and who I work with when I'm not around here. And it wasn't like that probably the first two years. But ever since then, I'm pretty comfortable and I feel good about it. It's kind of been pretty similar, and I rely on my trainer, and when I come back here I rely on these guys. I think it's working out really well."
