Redskins quarterback Colt McCoy indeed put up big numbers in his start in place of an injured Robert Griffin III Week 13 at Indianapolis. Of course, it wasn't until the Colts already had a commanding lead that he really started to play well.
After he threw for just 94 yards in the first half, his mobility became a major asset in what some would classify as a throw-every-down scenario, helping him elude the pass rush as he kept his sights downfield. He still took six sacks with the play calling somewhat telegraphed by the score, but he threw for 392 yards and three touchdowns with no interceptions, completing 31 of 47 passes. It was the Redskins' best individual passing performance since Kirk Cousins threw for 427 yards and three touchdowns in Week 3.
Of course, McCoy has had chances to start in the past, particularly with the Browns, and has mostly failed with them, so there's a chance this performance was more a product of the Colts' big lead that McCoy's ability or knowledge of the offense. In two-quarterback leagues, he's worth a flier, but in one-quarterback leagues, given the depth at the position, you probably wouldn't want to pin your hopes to him with this one performance.
