But they must realize they're only going to be remembered for one season, good or bad, and only at their new school. So they better make a splash.
The place where they went 3-4 years shouldn't waste time bringing them back for reunions.
Fact is, they transfer because they're good, meaning their original team could sure use them for another year. We could sure use Greenard.
So AFAIC if they leave? See ya.
To the ones coming in? Hope you're as good as touted. If you are, you'll be remembered fondly. If you're not? You'll be remembered by no one.
But that's just me.
