Key Players
Purdy's processing speed and accuracy within Shanahan's system make him one of the most efficient quarterbacks in football. His ability to identify and attack soft spots in coverage quickly is a genuine skill.
Murray's speed and agility make him one of the most dangerous quarterbacks in space. When healthy, his ability to extend plays and create out of structure gives Arizona an explosive element.
McCaffrey's versatility as both a runner and receiver out of the backfield creates matchup nightmares for linebackers and safeties. He is the offense's most important player and the focal point of every defensive game plan.
Harrison Jr. brings elite physical tools to Arizona's passing game. His combination of size, speed, and polished route running makes him a legitimate star.
