Why is the "rookie" excuse okay to pin on Clausen but the remaining rookies on the field don't seem to be having problems... unless those problems are specifically related to the QB getting them the ball.
The 3rd down and 17 5-yard pass play is not a rookie issue- it's an issue of him checking down the vast majority of the time.
then he needs to be taught not to.
there are errors that you can get away with in college that you can't get away with in the nfl. rookies have to learn (someone has to teach them) the correct way to do things.
clausen has no veteran leadership to guide him and apparently lacks a quality qb coach to teach him.
even the highly anticipated andrew luck would have problems under the same conditions.
