i'm assuming that he would have three and one half years of eligibility remaining. if he played the entire year last year, and then transfered, he would have three years left. so it doesn't make sense that he would have only two and one half years eligibility if he left after just playing half a year.
I originally thought the same
However, I believe that, by playing half of his freshman season, he burned that year
So, instead of three and a half years of eligibility, I believe that he has two and a half years left
If that's the case, he should have stayed at A & M for his entire freshman year
He would then have had 3 full seasons to play at his next school
