There is no telling how productive Maclin can be in Kelly's offense, but the presumption is he should be very successful. Jackson had a career year last year, catching 82 passes for 1,332 yards and 9 touchdowns. In the four previous seasons, Maclin never broke the 1,000-yard marker, but he also never was officially the Eagles' No. 1 receiver, even if he was the more well-rounded player.
Given the way Kelly likes to throw the ball and run an up-tempo style, there's no reason Maclin can't emulate Jackson's numbers from last season as long as he can stay healthy.
The Eagles certainly aren't done with the wide receiver position, either. They very well could make a play and move up in the draft to select Clemson's Sammy Watkins or Texas A&M's Mike Evans. Or they could stay patient at No. 22, select the best player available and take a receiver later in the draft, perhaps Florida State's Kelvin Benjamin, who is considered a project but, at 6-foot-5 and 240 pounds, has great size.
There is an interesting transformation ongoing in the Eagles' locker room. The leadership is changing. Quarterback Michael Vick was the unquestioned leader of the team, but he now will be fighting for a starting job with the New York Jets. Wide receiver Jason Avant was so revered for his leadership -- particularly in the wake of the Cooper fiasco last summer but also during the competition between Vick and Nick Foles for the starting quarterback job -- that the team put out statements from owner Jeffrey Lurie, general manager Howie Roseman and Kelly after the team released him.
They didn't do that for Jackson.
At the NFL owners meetings in Orlando, Fla., last week, Kelly was asked about the leadership void. He acknowledged that the Eagles had "two great ones" in Vick and Avant, but he also mentioned ascending players such as linebacker Connor Barwin, center Jason Kelce and newly acquired players such as cornerback Malcolm Jenkins and running back Darren Sproles.
"That's a big component in evaluations when we're adding to our team," Kelly said.
You can add Maclin into that equation. He is not yet 26 years old, but he has the potential to be a level-headed team leader who doesn't question authority, plays hard and has his teammates' respect. Jackson wasn't that, which is why the Eagles opted for addition by subtraction.
