Patrick Mahomes has spent just a few days with the Kansas City Chiefs, but he's already a little overwhelmed by the team's playbook.

"It's a lot more than I had at Texas Tech," Mahomes said. "Whenever I got up there and called it, then I had to look out there and see the guys and make sure everybody was in the right position. That was pretty much the process, and it was a lot harder than I thought it was going to be."

Alex Smith is expected to remain the starter for the Chiefs as Mahomes develops.
