Jackson was one of the top wideouts available in free agency once San Diego decided not to give him the franchise tag. It didn't take him long to hook up with Tampa Bay and quarterback Josh Freeman, in whose honor Jackson got all those 5s in the deal; Freeman wears uniform No. 5.
The contract, negotiated by Schwartz and Feinsod Agency, will pay Jackson $13 million in each of his first two years, then $10 million for the third year.
San Diego gave Jackson the franchise tag in 2011 and he signed for nearly $11 million. He missed most of the previous season in a salary dispute.
During the lockout, Jackson was one of 10 named plaintiffs in the Brady V. NFL antitrust suit filed against club owners.
Then Jackson had his third 1,000-yard receiving season in 2011 on his way to his second Pro Bowl. He made 60 receptions for 1,106 yards and nine touchdowns, and Jackson's yards per catch average of 18.4 was sixth in the league.
