Key Players
Allen is the most physically gifted quarterback in football. His combination of arm strength and rushing ability gives Buffalo a weekly chance to beat any team in the league.
The reigning standard-bearer at the position. Mahomes' combination of arm talent, mobility, and football IQ makes him nearly impossible to game-plan against consistently. Look for him to exploit single coverage and generate explosive plays in the second half.
Diggs' route precision and contested-catch ability make him Allen's most reliable target in critical moments. He wins on all three levels of the field and understands how to manipulate cornerback leverage.
Kelce remains the most reliable tight end in football in critical moments. His route running in the middle of the field and red-zone presence gives Mahomes a safety valve that defenses cannot fully eliminate.
