Some people think that Andy Reid’s offensive brilliance is responsible for Mahomes’s success. It’s true in the sense that every elite quarterback benefits from a stable coaching presence. Look at Trevor Lawrence and the nightmare he dealt with in Jacksonville after the appointment of Urban Meyer.
However, it’s stupid to say that Reid is the only reason why Mahomes is brilliant. After all, Mahomes was a first-round draft pick and had an excellent record with Texas Tech. Then he came within a breath of playing in a Super Bowl in his first season as a starter (via Clutchpoints).
