McCarron posted a 63.8 completion percentage at 6.7 yards per attempt for a 89.7 passer rating in four starts as Andy Dalton's stand-in late in the 2015 season. Although he showed initial promise under then-play caller Hue Jackson, he failed to convert a single third down in the regular-season finale and was shut out for three quarters in the rain as the Bengalslost a memorable playoff bout with the Steelers.
