Now it can be revealed. When Aldon Smith visited the 49ers for his first get-to-know-you visit, the team made him take a written test of 50 questions. He admitted to the media he got at least two wrong.

What is the width of a football field? He said 50 yards. It’s 53 1/3 yards. I had to look it up.

Who was Knute Rockne? Smith didn’t know. Wasn’t Rockne the guy who invented the Caesar Salad?

I still don’t understand why the Niners made him take that test.
