You guys need to separate being a great college QB at the FCS level vs. being an NFL prospect. Hackenberg is considered a top NFL QB prospect because he is 6'4", 230 and has a rocket arm.
Robertson is a great athlete and accurate passer and the top FCS player. But at the end of the day, he just doesn't have the arm strength or size for the NFL.
There are truly great QB's who just don't fit what the NFL is looking for. The list could go on forever.
Why even bother comparing Robertson to Hackenberg. It's apples to oranges. Also, let's see how successful Robertson's game would be if he were chased down by Ohio State defenders who are 6'5", 260 and run a 4.5 40 yard dash instead of Albany defensive players.I love Robertson, but the comparisons and NFL potential are getting a bit tired.
His game just doesn't fit what the NFL is looking for. Even the new style guys like RGIII, Kapernick and Wilson have big time throwing arms to back up their running mobility.
