Derrick Gordon is leading the country in free throws made (37) and is second in free throws attempted (44), while ranking 172nd with an 84.1 percentage. Although that is a misleading stat because the minimum to qualify for the rankings is 2.5 makes per game. Either way, anyone who has watched DG shoot free throws last year and this year will tell you that his stroke and results are night-and-day from each other.
Nick Canelas of MaroonMusket.com has an article on DG at the line and how much effort he has put in to that part of his game since last season.
