Just curious as to why the Byron Buxton Live card has a speed rating of only 69.
According to
https://baseballsavant.mlb.com/sprint_speed_leaderboard, he has the fastest average sprint speed of any player in the majors this year, and has been first for 4 of the last 5 years (2nd in 2017).
He's also in the top 5 of the fastest Home to First times in 17 and 18.
He's consistently ahead of guys like Mondesi and Hamilton who both have 100+ speed.
