Mack struggled with an injury in training camp, but once he got going, he really got going. He had five games where he ran for at least 119 yards and a touchdown and saw at least 10 carries in all but two games. He was not as involved in the passing game (1.4 receptions per game), but the Colts did have him running more routes late in the year, possibly signaling that he’ll have three-down duties in 2019. He averaged a total of 87 yards and 0.79 touchdowns per game in 14 games, including the postseason. Andrew Luck's retirement is obviously a big blow to the whole offense, but Mack should remain one of the team's offensive centerpieces. He's more of a fifth/sixth round pick without Luck.
