Now 33 years old, Jackson was viewed as a potential cap casualty after battling knee, rib and wrist injuries over the past two seasons. He failed to reach 1,000 yards last season for the first time since 2010.
The Bucs will retain Jackson for several reasons. He's a team leader suited to Dirk Koetter's offense. That's hard to replace in a weak free-agent market and a below average draft class for wide receivers.
Winston's offensive attack also averaged 22.3 points per game with Jackson in the lineup last season compared to 19.6 points per game with Mike Evans' running mate sidelined.
