All it took was about two years of acting like a complete jerk.

ESPN’s Adam Schefter reports that the contract is worth $51 million over five years. Meanwhile, ProFootballTalk pegs the base salary a little lower at $47.5 million with $15 million guaranteed, but Mike Florio indicates that Jackson can reach Schefter’s $51 million mark through escalators and incentives. Jeff McLane of the Philadelphia Inquirer echoed those numbers, saying that Jackson has a chance at $51 million.

So we’ll just agree that it’s somewhere around $50 million, with a yearly cap hit of approximately $10 million.

Florio also has a full breakdown of the contract details, and here’s the money line:

In the end, Jackson swapped a one-year, $9.4 million guaranteed franchise tender in exchange for another $5.6 million in fully guaranteed money — and $3 million more in money guaranteed for injury only.

The lack of a long-term commitment was the catalyst for Jackson’s chronic bouts with locker room sulking, and just general sulking. Now he has that security, and in theory he should be happy and joyful.

But have the Eagles just paid to satisfy a player, instead of paying what the player is worth? Sure, Jackson is dynamic, and brings an explosive presence to the return game, which escalates his value a little higher than the average speedy wideout who’s a deep threat. That’s terrific, but Jackson has quickly grown to epitomize the boom or bust wide receiver.

He finished with 961 receiving yards this year, which was only slightly less than his 2010 total (1,056). But his yards per game dropped by over 10 yards (75.4 to 64.1), primarily because nearly 30 percent of Jackson’s 2011 yardage came between just two games. On the other extreme, he had six games with less than 40 yards.

If he plays through the life of this contract, Jackson will earn about $125,000 in guaranteed money per game, and it’s difficult to determine which Jackson will show up on any given Sunday to earn that paycheck.
