re: How is Johnny Manziel a RS freshman if he's a junior in school?

He also enrolled early. He finished HS in three and a half years and enrolled at A&M in January of his senior year in high school, to get spring ball in. So, while he is only a freshmen in terms of eligibility, he has been on the A&M campus for 4 semesters now. Add in summer school, and he is a Junior academically.
