There is plenty of optimism surrounding the Indianapolis Colts this offseason with the addition of head coach Frank Reich, as well as the progress of quarterback Andrew Luck’s health. Meanwhile, Marlon Mack is looking forward to potentially taking on a lead back role in the 2018 NFL season.

With the departure of running back Frank Gore, Mack is now poised to take on a much larger workload this season. However, according to Andrew Walker of the team’s website, he is well-aware that the other running backs on the team share his same desire:

“I feel like, for me, it just motivates me to just go harder,” Mack told this week. “Other guys in the room feel the exact same as me. Everybody wants to be the top dog, and so you’ve just got to (be motivated) and just be hungry and attack; attack, I’d say, just show your talents and do your best.”

Mack served as the complementary back to the veteran Gore throughout his rookie season. The Colts selected the former South Florida product in the fourth round of the 2017 NFL Draft and it was not long before his big-play ability quickly earned him the backup job.

Mack garnered 358 yards on 93 rushes for three touchdowns during the 2017 campaign. He also managed to flash his versatile skill set by hauling in 27 receptions for 225 yards and a touchdown. That said, he certainly checks out a number of boxes when it comes to becoming a three-down back.

However, he will face some stiff competition from the other running backs on the depth chart looking for an increased role such as Josh Ferguson, Matt Jones, and Christine Michael.
