Here is my thought process. A comparison of our two in question.
Throwing the ball:
Jimmy: A spiral.
Jon: A spiral.... in the dirt.
Running the ball
Jimmy: Runs for 4 yards, and slides to avoid contact, insuring his brain cells.
Jon: Runs for 9 yards, and gets knocked into oblivion, avoiding serious brain damage because like the scarecrow, he has no brain.
Handing the ball off
Jimmy: Learned this when he was 7.
Jon: Waste of time, lets just go long.
Press conference
Jimmy: Humble, quiet, team player.
Jon: Resembles Russell Hammond in "Almost There" saying "I am a Golden God." and enjoys telling the fans they're not needed.
Intelligence
Jimmy: Can effectively operate a playbook, and read defenses.
Jon: Has had our playbook stripped to 25% of plays, can't read defenses, and has a reading level of a 7th grader.
In a close fought match.... the title of better QB, is Jimmy Clausen.
