Patrick Mahomes says the Kansas City Chiefs have already made significant additions to their playbook this offseason.

"We've added a lot. We never stop adding plays here. That's the best thing about this team, this offense: We're never satisfied with where we're at. We're always trying to get better, finding ways to get better as a team, as an offense," Mahomes said.

He was named the NFL's MVP in his first season as Kansas City's starter.

"There's still a ton that I need to improve on. There really is. I made a lot of plays happen kind of off-script, but there were times I should have just made the easy completion for the first down. So I have to keep finding that line of when I want to make the big play happen and when I should take the easy completion," Mahomes said.
