Lions linebacker Jack Campbell reveals what he's working on after good showing in preseason opener

The Detroit Lions' rookie class impressed as part of their 21-16 victory over the New York Giants in Week 1 of the preseason, and Jack Campbell was one of the best youngsters on the field.

Campbell shined when he was given time to run with the defense, posting four total tackles and defending one pass. But while he didn't look out of place at all in his first game, Campbell came away knowing he had several things to work on.

Speaking to the media after the game against the Giants, Campbell was asked to evaluate his first game. Here's his breakdown:

"(I worked on) cleaning up some communication stuff, cleaning up some technique stuff and that's something I'm always going to work on, especially for me, my pad level. Also, just stepping out there as a rookie, just having confidence in yourself play in and play out, like that's kind of what I'm focusing on right now."

Campbell will have the chance to keep improving, and while it was a good start, it's also encouraging he wasn't close to satisfied with the effort.

Jack Campbell revealed his "Welcome to the NFL" moment

Many players have a specific moment in a game where they realized the step up the NFL is. Campbell didn't seem to think he had one against the Giants though.

Instead, Campbell went with a moment in practice for his "welcome to the NFL" moment.

"I would say my welcome to the NFL moment was when Tom Kennedy caught a ball on me earlier in the year. Just how precise the quarterbacks are and how precise the receivers are, just being able to throw it on the back shoulder. For me as a linebacker at the college level, I feel like not a lot of people can do that. But now that I'm here, getting the opportunity to go up against Jared Goff, (Nate) Sudfeld and Adrian Martinez, they can put the ball wherever they want. So that'll be a challenge, but that's something that I'm looking forward to."

Clearly, Campbell has had his eyes opened in plenty of ways coming into the league. Hearing how he understands what he must work on even after a very solid debut is a breath of fresh air, and the coaching staff was surely glad to hear it too.
