Tom Brady sprinted sideline to sideline alongside fellow quarterbacks Tim Tebow and Ryan Mallett after the seventh day of the New England Patriots' training camp.
Despite turning 36 yesterday, more than a decade older than both of his backups, the Patriots' franchise quarterback was able to keep pace with the others, even saving enough energy to sign autographs afterwards for fans.
Kind of like Tebow, whom Brady seems to be helping learn New England's offence.
"We have good conversations," Brady said. "He loves playing football, and that's usually the type of guys who do well here."
Tebow is relishing the opportunity. "Working out here every day together and trying to push each other," he said.
"It's awesome because you're getting to work with one of the best of all time."
Brady is working with several new pass catchers this season after his top five receiving leaders from last season are no longer with the team or are injured.
Wes Welker signed with Denver, Brandon Lloyd is no longer with the team, tight end Rob Gronkowski is sidelined indefinitely after undergoing back surgery in June, tight end Aaron Hernandez was released after a murder charge, running back Danny Woodhead signed with San Diego, and veteran receiver Deion Branch is a free agent.
That leaves Brady with Danny Amendola, who will likely fill Welker's role in the slot, Julian Edelman, who caught 21 passes last season and practised on Thursday for the first time since fracturing his foot in December, and veteran Michael Jenkins. Also included are several youngsters, five of whom were just 10 years old when Brady first entered the league.
"It's about us trying to use what they do best and trying to get them incorporated and them finding a role for themselves," Brady said.
"When you really believe in the guys you're out there with, you can play fast, you can play with anticipation, you can play with confidence. If you don't have that confidence, it slows you down, and then when it slows you down, then you're going to make mistakes."
Brady is willing to live with those miscues - even his own.
"We all make mistakes. I make them, the young players make them, everyone makes them. The Jets are going to make them, the Dolphins are going to make them, the Bills are going to make them," he said. "It's just a matter of how critical those mistakes end up being. Hopefully our bad plays are incomplete passes and are not really bad plays."
Brady, the oldest member of the Patriots and one of just two players on the roster born in the 1970s, is two years removed from his fifth Super Bowl appearance and fresh off a run to the AFC championship game last season.
The two-time league MVP last season broke the 4,000-yard mark for the fifth time in his career - and the third time in the past four seasons - throwing for 4,827 yards and 34 touchdowns with just eight interceptions, tying for the second-lowest total of his career.
"I feel better as camp goes along. Every day I feel like my legs get more under me, my arm gets better, so I'm enjoying it."
