Written off by many after a disastrous 2023 rookie campaign, Johnston made major contributions to the Chargers in 2024 and 2025, putting up receiving lines of 55-711-8 and 51-735-8. Drops have been an issue, and his target volume hasn't been consistent, but Johnston has done well with his downfield opportunities overall, scoring eight TDs the past two years on targets traveling 20-plus yards downfield. Last year, Johnston seemed to be breaking out early in the season, with averages of 5.2 catches for 75.4 yards and 0.8 TDs over the first five weeks (8.0 targets per game). He then missed Week 6 with a hamstring injury, slumped during the middle of the season, and was inconsistent down the stretch while dealing with an injury-ravaged offensive line. Johnston's season-long average of 12.5 PPR points was a career-high, but he averaged just 9.0 PPR points and 37.8 yards over his final 10 games (including playoffs). He'll have a chance to get back on track under new Chargers offensive coordinator Mike McDaniel, though 2025 second-round pick Tre' Harris could perhaps make a bid for Johnston's starting job if Johnston struggles in the new system.
