Just an article I saw on Yahoo! showing the transformation of players from the time they were freshmen to the time they were drafted by an NFL team. There's a table showing the recruiting weight and the draft weight. Julio Jones and Jon Baldwin both actually lost weight. Nick Fairley, Nate Solder and JJ Watt put on the most weight at +57 +65 and +65 respectively (maybe they just ate a lot?)
I just have a question, how much, if any, did these guys grow. Because between end of my senior year of high school and senior year of college, I believe I put on about 60 lbs and 6 inches of height.
