Baltimore Ravens quarterback Joe Flacco has been impressed by the impact that veteran duo Brandon Stokley and Dallas Clark have had since joining the franchise.
Wide receiver Stokley, 37, joined the Ravens on a one-year deal at the end of last week before tight end Clark, 34, followed just a day later as the reigning Super Bowl champions went about bolstering their offence before the new season.
The duo have both enjoyed lengthy careers in the NFL, and Flacco claimed that it was easy to see why despite their advancing years.
"You can definitely tell why they've both been in the league as long as they've been in the league," Flacco told ESPN.
"They have a special quality about them and the way they run their routes and the way they catch the ball. Brandon, especially for being in the league as he has, he can still run and his legs definitely look fresh.
"I'm definitely excited about it, I'm really excited about the progress of the offence as a whole. I think these guys will fit in and play their role pretty well."
The Ravens will kick off their title defence at the Denver Broncos on September 5.
