It is very, very rare for a player to fail at quarterback in the NFL, then become an effective receiver.
But Terrelle Pryor of the Cleveland Browns is a special athlete, and he might be in the process of pulling it off.
Pryor made a pretty nice statement on his first play this preseason, in a 17-11 loss to the Green Bay Packers. Pryor ran a go route, got separation from Packers cornerback Damarious Randall (a 2015 first-round pick coming off a nice rookie season) and grabbed a 49-yard pass from Robert Griffin III. Pryor also converted a third down later in the drive.
