I rewatched the 2 plays that Justin Rodgers had in the Cheese It Bowl. I want to take back my previous comments. He really did a good job on a limited amount to review.
First play: he had a defensive player bounce off of him and he ran to about the line of scrimmage. His running wasn't horrible. IMHO, it seemed that he might have previously had another gear of speed that wasn't there when he took off. Think his running was adequate and could improve with time.
Second play: completes a little pass off to the side. Foot work looked good. Coaches could have called a safe play and just called a hand off to the RB. But coaches trusted him to throw the ball in a tough bowl game in the 4th quarter.
Both plays were supposed to be passing plays. This causes me to think he is ready. Furthermore, IIRC he wasn't even cleared to play until Nov? I remember seeing an article from the startlegram to something of this nature.
Kid has a monster arm which seems pretty accurate. If he could get an oline that can give him time and keep him standing upright he could be slinging the rock all over the field.
