NFL rookies have finally settled in with their new teams following three weeks of OTAs and minicamps. Now more than a month removed from the draft, they’re getting acclimated to the ins and outs of being a professional football player.

Los Angeles Rams rookie running back John Kelly is among them after being a sixth-round pick in this year’s draft. As the youngest player in the Rams’ class, Kelly admits he’s “got to mature for sure,” saying rookies have “a bigger target” on them now than they did in college.

Fortunately for him and the rest of the Rams’ draft class, Sean McVay has created a culture in Los Angeles that makes young players feel comfortable and confident that they can contribute in Year 1. After all, the Rams got plenty of production out of their rookies last season with the likes of John Johnson, Cooper Kupp, Gerald Everett, Samson Ebukam and Josh Reynolds all making contributions in one way or another.

Kelly is already recognizing the culture McVay has established and he likes what he’s seen.

“With coach McVay being a younger guy, he can relate to us a lot more and we have a nice group of older guys who’ve been in this league for a long time as well,” Kelly said, via TheRams.com. “I feel like we got a culture that’s like no other. As far as me being here and me taking visits to other places, I feel like coach McVay did a good job of developing a great culture here. We’re all caring and loving on each other every day, but we’re also competing every day at practice.”

Kelly joins a running back room that’s relatively young. Todd Gurley is just 23 years old, while Malcolm Brown is only 25. Justin Davis, an undrafted rookie in 2017, is 22 years old and has very little tread on his tires.

Kelly says all three have been “pretty helpful” thus far and that he’s learning “at a nice tempo.” Whether that translates to production in Year 1 remains to be seen, but he certainly has a chance to be Gurley’s primary backup.
