THIS WAS GOING to be a column about DeSean Jackson learning a new offense under coach Chip Kelly and maybe, just maybe, finding a way to unlock what can be a devastating skill set with a little more regularity. It still is going to be about that, too - after a short detour.

Because here is the thing: I could not care less about the identity of Jackson's agent. When word broke the other day that he was firing Drew Rosenhaus and maybe signing on with Jay-Z, my only reaction was to click on the next story as soon as humanly possible.

Now, though, we have more news. Yahoo! Sports is reporting that Rosenhaus has filed a grievance with the NFL Players Association, claiming that Jackson owes him $400,000. Seeing as how he signed a deal last year that could end up paying him about $50 million, this would not seem to be an insurmountable issue.

But it is a public issue now, another ripple on the pond. It is all part of the DeSean Jackson Experience, as everyone knows.

"Right now I'm just focusing on football, honestly," Jackson said yesterday afternoon, before the Yahoo! Sports report broke. "I haven't made a decision on where I'm going or what I'm going to do yet. That's not really important to myself right now. The most important thing is this season, my teammates and this team. Winning games and putting in the work to do the things we need to do to go into the season and have a head start on everybody else."

With that, end of detour.

Jackson used the phrase "putting in the work." He also admitted that when Andy Reid was the Eagles' coach, "For myself, I never really made it throughout the whole offseason workouts." He didn't want to do them, it seems, and besides, there wasn't a whole lot of learning necessary after his first season. The offense was the same, the coach was the same, the day-to-day schedule was the same.

Jackson usually thrived within that static structure. He put up some numbers, and he eventually got paid. And if he was invisible in the red zone, and occasionally self-absorbed beyond the understanding of most, he remained a player who always needed to be accounted for by opposing defenses.

For years, that was enough - but now it isn't enough anymore. It is the lesson of Chip Kelly, who is called (in alternating sets of clichés) either the new sheriff in town, the new broom who will sweep clean, or the new set of eyes.

Whatever - he has Jackson's attention.

"This year, having Chip come here, I've been here throughout the majority of the workouts and have been putting in the work with my teammates and things like that," he said. "So it's a good thing right now."
