Collins enters his sixth NFL season without a full 17-game campaign but has been highly productive when available. The 2021 third-round pick has exceeded 1,000 yards and scored seven or eight touchdowns in each of the last three seasons, finishing in the top 10 in fantasy PPG and top 12 in yards per route run all three years.
