The Keenan Allen trade officially came full circle for the Chicago Bears and Los Angeles Chargers on Tuesday, nearly 18 months after it was initially made. Allen is set to re-sign with the Chargers on a one-year deal worth over $8 million, bringing him back to the team he called home for 11 seasons.

The Chargers were looking for veteran leadership in the receiver room, and there's no one better than someone who has spent so much time with the franchise. However, the relationship between Allen and the Chargers hasn't always been roses.

Free agent wide receiver Keenan Allen and the Los Angeles Chargers have agreed to a contract in free agency, the team announced Tuesday.
