WR AJ Green (Bengals)
There’s a world where the 49ers are able to retain some of their free agents and fit Green in under the cap. He turns 32 before the start of the season, and missed all of 2019 with an ankle injury. Green is exceptionally productive when he is on the field, averaging 75 catches, 1,113 yards and eight touchdowns per year during his first eight seasons. The 49ers badly need another playmaker on the perimeter across from Deebo Samuel, and Green is as good a receiver as there is in the league when he’s healthy.
