But with training camp arriving in less than a month, Gates remains a free agent and the Chargers still need a tight end.
Tomlinson would have some insight on Gates' mindset when considering the two were teammates for seven seasons.
While Green, who joined the Chargers on a three-year deal during free agency, enters his eighth season, he has just 71 career catches for 807 yards and four touchdowns. The remaining tight ends on the team's roster ahead of training camp are Braedon Bowman, Sean Culkin, Cole Hunt, Ben Johnson and Austin Roberts.
On his career, Gates has 927 catches for 11,508 yards and 114 touchdowns.
