"Down, up, 1. Down, up, 2. . . ."
Jackson was at Moorestown Upper Elementary School for his third annual football camp for local youth ages 7-16. He arrived an hour after the camp started and walked across the field, stopping to help coach the players broken up into five groups based on age.
"Growing up, I used to attend a few NFL camps," Jackson said. "Honestly, it's a blessing. It's more physical than anything else. They can talk with and learn from and be inspired by an NFL player."
He threw passes to the two youngest groups. He told a group of preteens to keep pumping their arms as they went through agility drills. And he worked on strength and conditioning with the oldest groups.
Jackson also talked about the Eagles and the three remaining weeks before training camp opens on July 22.
"Everybody knows our skill and how close we've been in the past," Jackson said. "Contracts are out of the way now and we have one common goal now."
Jackson's agent, Drew Rosenhaus, was on hand, wearing a shirt with the word "staff" on the back, though he spent much of his time on the sideline talking on the phone.
"DeSean is very committed to being a role model," Rosenhaus said. "This time last year, we didn't know what his future was going to hold. Now he's able to just focus on football."
Here, the drills aren't any different than the ones these players learn at football practice. But the person running them is a hero to many of these young athletes - a hero who has the power to demand a few more push-ups out of a tired teenager.
