Quarterback Alex Smith is having the best season of his career. Tyreek Hill’s numbers as a wide receiver are up over last year. With one more interception, cornerback Marcus Peters will match last year’s totals. Linebacker Justin Houston has surpassed his sack total from 2016. The statistics line for each player provides the proof. But what about the Chiefs players for whom few recognized statistics exist? How, for instance, can one measure the season of fullback Anthony Sherman, who has no rushing attempts, three receptions and a lone special teams tackle? For starters, there’s the testimony of his coaches. “He’s our heart and soul,” special teams coach Dave Toub said. “Solid player. I can count on him. I can put him anywhere, it doesn’t matter.” Offensive coordinator Matt Nagy calls Sherman, who has spent five of his seven NFL years with the Chiefs, an ideal fit in the Andy Reid offense.
