"Our goal will be to be a top-five, top-seven, rushing team," Reich said this week at the Annual League Meeting in Phoenix, via the team's official website.
The Colts have a big leap to make to accomplish that goal. Indy finished 20th in rushing yards with 107.4 per game in 2018. The team's 4.2 average per rush finished 21st in the league.
Reich wants a consistent running game to help keep defenses off balance.
"I just have a really strong conviction of that's what it takes," he said. "In this day of high scoring, crazy pass offenses, and that's all true, but if you look at the numbers, you gotta be good at running the football. There's exceptions to that, but the percentages are with you... if you're a top-10 rushing team, you gotta much better (chance to win)."
With Indy not yet adding to the trio of Mack, Nyheim Hines and Jordan Wilkins this offseason, Mack's health will be key for Reich to accomplish his goal. The 23-year-old compiled 908 rushing yards in 12 games in 2018. The Colts struggled sans Mack last season, losing each of the four games the running back missed.
A shifty speedster who can make quick cuts and change gears in the hole, Mack is poised to take the lead role in 2019, if he remains healthy.
Reich noted he'll continue to utilized a committee approach, "but Marlon's a little bit more the featured guy"
"He's got burst, he's really smart," Reich said of Mack. "And Marlon, he's got burst and he's got that speed, but he's a good inside runner. He's got good play strength -- that's one of the phrases we talk about; what's his play strength like? He's got good burst, he's got good vision."
