Here are some quotes from an article i found on it.
"The thoughts of a grayshirt was something Jared McCray did not expect to hear prior to the Thanksgiving holiday.When coaches from Louisville told the Minford offensive lineman of the Cardinals’ intentions, he informed them of his plans to decommit and reopen the search for his college home next fall."
“After looking at it and thinking about it, I really didn’t want to sit out a year of college football if I have that opportunity,” McCray said. “I just want to play football and just sitting out a year was not anything that comprehended in my mind. I just decided it was time to move on and hopefully another spot would open up for me to play football in that first year.”
