When I started compiling this list, I wasn’t sure where to put Mason. It was actually his insane 2017 season that got me thinking about the top 50 (or so) Jayhawks of all time, and how remarkable it was that a kid who was so lightly recruited became one of the best players ever at a program like Kansas.
When I got down to it, it was pretty obvious he needed to be in the top 10. Mason currently is all over the Big 12 career leaderboards, ranking 10th in career win shares, 12th in Box plus minus, 4th in offensive rating, 22nd in assist rate, 20th in true shooting percentage, 7th in assists, and 2nd in both games and minutes played.
