" One trick I use (I think I may have invented this, I never saw anyone use it before I did) is to redshirt a Juco. In order to do this, you MUST inform him of redshirt during recruiting "
This is not true btw. I've definitely had a JR JUCO take a RS without telling him about it beforehand. Maybe it's rare, but it's not set in stone. He did have 90+ WE, so maybe that made a difference.
And I have to admit I laughed at the part in parentheses. How could you possibly have any idea whether that's true or not?
