The best coaches, imo, are the ones who are so intelligent that they would succeed in any career path. There was a good article on Grantland comparing Smart and Stevens. I believe it said Smart almost had a perfect SAT score.
Some of the truly great coaches fall under that category.
yea he also graduated magna *** laude from his undergrad and did his masters on a full scholarship. He's also a big history buff and wrote his masters thesis on race issues in the US during the Great Depression. Seems pretty smart.
