Isiah Pacheco led the Kansas City Chiefs in rushing (830 yards) as a rookie, but the running back sees room for improvement heading into Year 2.

He also had 197 yards in the postseason run and a Super Bowl touchdown.

"As a seventh-round pick, I always had something to prove, for the doubters," Pacheco said. "If you dream big, you could go get it, go grab it. That's something I always had in mind of being on this stage, on this level. It feels unreal, but it's real and it's here and so I have to embrace it."

Kansas City used a seventh-round pick to draft Pacheco last year.

"Being able to extend the things I'm able to do, that comes with work in the offseason," he said. "For me, I still feel like there's more to improve … I'm satisfied with the [Super Bowl] win on my first [appearance], but I'm unsatisfied because I know that there's more that could've been done out there.

"One of the [biggest] things I improved on, [is] eliminating the distractions. I could have a thousand things going on, a lot of people hitting my phone up. I just kind of sit it on silent, sit it to the side. When it's time to work, it's time to work."
