It was fair to question if the Kansas City Chiefs offense would be as strong in Patrick Mahomes' first season as the starting quarterback as it was with veteran Alex Smith under center in 2017.
The team's new franchise quarterback has the size, strength and mobility to become something special, but Mahomes attempted just 35 passes as a rookie, he's risk-taker who will likely always be prone to mistakes, and he made several notable miscues this summer.
Meanwhile, that Smith-quarterbacked Chiefs offense was one of only two in football to average more than six yards per play, and Smith was the league's highest-rated passer in 2017.
