Academics are a better proxy for discipline, grit, and upbringing than for intelligence. There's a little more overlap between recall and intelligence (smart people often have strong ability to recall important facts). However, if you've ever met a dumb person with encyclopedic sports knowledge, you've encountered the counterexample.
Intelligent people are drawn towards knowledge because knowledge makes decisions more efficient and effective. There are many other reasons to be drawn towards knowledge, and many intelligent people don't feel academic knowledge is vital to their specific success.
