The article focuses on college football, but as we fans know, it seems to apply to college basketball as well.
Also, if you look at the chart (which is about 3/4 of the way through the article) it shows that in 2016, there were 117 grad transfers in football and 87 in basketball. Basketball had 74% of football's total. BUT, when you take into account that a football team has 85 scholarship players and a basketball team has 13 scholarships, you'll see that basketball has just 15% of football's total. I would think that that indicates it's the grad transfer rule that is being utilized MUCH more in basketball.
