Kiper picks out first-round rookies who will play immediately

The 2017 NFL draft is over, which means we're one step closer to my preseason All-Rookie team. The first-round picks featured on last year's team? Ezekiel Elliott (✔), Jack Conklin (✔), Leonard Floyd (✔) and Joey Bosa (✔), among others.

It was a great 2016 rookie class, especially in Round 1, but no fan base should assume his/her favorite team is getting a superstar from Day 1. Teams draft to fill needs, but rookies -- even first-rounders -- aren't likely to fill them above a league-average level, for the most part. Last year's class had a few notable exceptions.

"Early impact" is more about having a clear role, not coming in and dominating.

With that in mind, here are six rookies from Round 1 (three on offense, three on defense) of the 2017 draft who I think will have a clear role early on -- or at least an opportunity -- along with a few notes on other players. I'll hit Rounds 2 and 3 on Wednesday and then run through Rounds 4 through 7 on Thursday.
