Last year the NFL's two leading rushers, Dallas' Ezekiel Elliott and the Bears' Jordan Howard, were rookies.
That may not happen in 2017, but this year's crop of rookie running backs sure got off to a hot start.
That included Howard's backup, as Tarik Cohen made quite the debut in the Bears' 23-17 loss to the Falcons. The 5-foot-6 Cohen caught eight passes for 47 yards and a touchdown and rushed five times for 66 yards. It was quite the coming out party for Cohen and gives the Bears a solid young 1-2 punch in the backfield.
Here's how Cohen stacked up against some other rookie running backs who had stellar debuts (listed by round selected):
Leonard Fournette, Jaguars (1st round): The Texans knew the Jaguars had little to offer in the passing game, yet Fournette still ran with ease. The No. 4 pick rushed 26 times for 100 yards and a touchdown, while also catching three passes for 24 yards.
Christan McCaffrey, Panthers (1st round): Jonathan Stewart actually had a better Sunday afternoon, but McCaffrey still showed flashes. The No. 8 pick had 13 rushes for 47 yards and added five receptions fo 38 yards. He did lose a fumble but it didn't mean much in a 23-3 Panthers victory.
Dalvin Cook, Vikings (2nd round): Cook made Vikings history on Monday night, rushing for 127 yards on 22 rushes and adding three receptions. The rushing yards were the most for a Vikings running back in his debut, topping Adrian Peterson's 103 yards in 2007.
Alvin Kamara, Saints (3rd round): Kamara's numbers weren't great (seven rushes for 18 yards, 4 receptions for 20 yards) but he led the Saints in carries, rushing yards and snaps played (41). That includes Adrian Peterson and Mark Ingram. The three-headed monster didn't mean much in their Monday Night Football thumping in Minnesota, but Kamara looked solid and Sean Payton clearly trusts him.
Kareem Hunt, Chiefs (3rd round): Whoa. The NFL regular season began with Hunt putting together one of the best debuts in NFL history. Hunt ran 17 times for 148 yards and a touchdown, and added five receptions for 98 yards and two scores. He lost a fumble on his first carry (after never doing so in college) but more than made up for it in perhaps the top performance of the week.
Marlon Mack, Colts (4th round): The Colts looked abysmal in their Week 1 loss to the Rams. Mack had an up-and-down afternoon, scoring on a 3-yard run but also committing a fumble that resulted in a safety. We'll throw him in here because he accounted for the Colts' only score in a 46-9 loss.
Chris Carson, Seahawks (7th round): In a backfield touting Eddie Lacy, Thomas Rawls (inactive) and C.J. Prosise, the rookie Carson looked the best in a loss to the Packers. he rushed six times for 39 yards, playing more snaps (26) than Prosise and Lacy combined (23). A terrible performance from Seattle's offensive line prevented Carson from doing much else.
