Montana was traded to the Kansas City Chiefs on April 20, 1993, and signed a $10 million contract over three years. His trade was the catalyst for the subsequent Chiefs' free-agent signing of star Los Angeles Raiders running back Marcus Allen on June 9. The arrival of Montana and Allen, both former Super Bowl MVPs, generated much media attention and excitement in Kansas City. Chiefs general manager Carl Peterson had spent the 1993 off-season installing the "West Coast offense" under the direction of new offensive coordinator Paul Hackett, who at one time served as 49ers quarterbacks coach to Montana, and who would report to incumbent head coach Marty Schottenheimer.
