Could have been a millionaire out of HS and possibly reached the Majors already, but listened to his parents (mom) and went to school instead. His arm would have still blown out, but at least he could have been paid first. Rocker's career goal was to reach MLB. He could have done that out of HS. Now he has an education that he may or may not have even cared about and it cost him 3-4 years of his pro career and millions of dollars in the process. Hitters choosing to go to college is more logical since the level of injury risk is much less, but for a pitcher to do it, especially when they could have conceivably gotten 1st round money out of HS, is a massive risk.
