He ended the first half of Monday night's game between the Cleveland Browns and Baltimore with 189 yards passing, and in one stretch completed 14 of 16 throws for 175 yards and a touchdown.
The first time the two teams played in October, McCown threw for a Browns record 457 yards. In six quarters this season against Baltimore, he's now passed for 646 yards with three touchdowns and no interceptions.
McCown's TD pass Monday night brought Johnny Manziel to mind. McCown dropped, felt the rush closing from the outside and tried to step in the pocket.
He was met by a Ravens lineman, so he stopped, reversed with his back to the line of scrimmage and then rolled left.
There he found Marlon Moore for a 10-yard TD.
The play involved plenty of good fortune. Moore was knocked to the ground as he crossed over the middle, but was able to get up unnoticed and run past the Ravens defenders to the side of the field McCown was rolling toward.
McCown finished the half 16-for-26 for 189 yards and one TD. His first half rating: 96.5.
