As part of the data gathered on one of the previous analyses, I ended up with some information on the size differences between the 3 categories of star-rankings for college football recruits. The sample size is 4,964 and covers the top 1000 or so recruits from 2015 to 2020.
The grey columns on the right of the height and weight tables are the standard deviations. The height and weight scores in the table are heat-mapped- darker green is a higher score, yellow is lower. All in all, it is easy to see that higher ranked kids are usually bigger in almost every position group.
