With a strong offensive line in place, Marlon Mack and second-round pick Jonathan Taylor are primed to benefit. Mack has been one of the best runners in the league since 2017, posting an 81.8 rushing grade and averaging an impressive 2.9 yards after contact per rush. He uses his above-average burst to get into the secondary and create big plays, as he has the 10th-highest percentage of breakaway (15-plus yards) runs since entering the league.
