Seven men have achieved the feat more than once : Peyton Manning has thrown four , Ben Roethlisberger and Kurt Warner have thrown three , and Craig Morton , Dave Krieg , Ken O ' Brien , and Tom Brady have two . Of these , only Roethlisberger has had more than one in a single regular season , when he had two perfect ratings in 2007 . Johnny Unitas , Joe Namath , Terry Bradshaw , Len Dawson , Bob Griese , James Harris , Bob Lee , Craig Morton , and Eli Manning had at least one game with a perfect passer rating and at least one game with a passer rating of zero , the lowest possible passer rating .
