Quentin Johnston was like the tight end nine, tight end 10... Right now, Quentin Johnston, as of the very end of May, is the tight end 16 overall... David Njoku's on the field in heavy packages. Quentin Johnston has an opportunity to be the move tight end with juice... Quentin Johnston's uh stats from last year, 660 receiving yards in a small sample size, that's more than David Njoku in almost every season of David Njoku's career.
STACKEDβs take
Fell to TE16 from TE9-10; 660 yards last year exceeds Njoku's typical output.
Quentin Johnston has fallen from TE9-10 ADP before the NFL draft to TE16 as of late May, creating a low bar for him to exceed expectations. JJ Zachariason attributes the market fade to the David Njoku signing but notes Njoku will be 30 years old and did not perform well last year. Zachariason expects Johnston to operate as the move tight end with juice in the Chargers offense, with potential to be a league-winner. Johnston produced 660 receiving yards in a small sample size last year, which exceeds David Njoku's receiving yardage in almost every season of Njoku's career (Njoku achieved that yardage total only two or three times maximum). This production comparison supports Johnston's upside in year two.
