Seeing him play in 2003 as a true freshman was painful.
I was actually pleasantly surprised at his having decent stats in his 2nd year (2004).
Tyrone Willingham insisted on running that stripped down version of the West Coast Offense, and his idiotic OC, Bill Diedrick, couldn't change a play on the fly to save his own hide.
It wasn't unusual that opponents with decent defenses knew what we were going to run even before we snapped the ball, especially since Diedrick tailored it to be a more run-heavy offense.
While it was certainly possible to run a WCO with a running emphasis (Jim Harbaugh did that at Stanford very well), the level of competence between Harbaugh and Willingham was rather sizable.
