3. Donald Parham Jr.
I'm aware that Chargers TE Donald Parham Jr. is technically not on next year's team as of right now. However, given the fact Parham is an exclusive rights free agent and is an incredibly promising young talent, the chances he's a Bolt in 2022 are greater than 99% in my opinion.
Despite Parham's scary injury in Week 15 against the Chiefs, the TE is expected to make a full recovery and be back on the football field next season.
Since the Chargers signed Parham out of the XFL prior to the 2020 season, the 6'8", 237 pound TE has been massively underused after finding himself buried in the depth chart. During his two seasons in the NFL, the Stetson University product played in 27 games and has hauled in 30 receptions for 349 yards and six touchdowns.
Parham's height advantage makes him a literal 'massive' target along the sideline, especially down in the red zone. Taking advantage of his speed and agility has been another under-utilized weapon in the Chargers offense but has worked well when schemed for. See his touchdowns against the Browns and Eagles as examples of this.
With Justin Herbert's laser arm and pinpoint accuracy, scheming increased targets for the 6'8" tight end should be of utmost priority for the Bolts heading into 2022. If they find chemistry with each other, then I truly believe Parham and Herbert could be a fantastic QB-TE combo for years to come.
With Jared Cook reaching the end of his career and no other TE1 on the roster, expect Donald Parham to take on an expanded role next year in 2022 and shine while doing so.
