Clint's older brother Nolan WAS a legit national prospect and a 4-star recruit to Texas. He played for the Longhorns for 3 years before quitting after his junior season due to multiple concussions.
When Brewster was hired as our coach, Nolan was a HS senior and 1 month away from signing his LOI with the Longhorns. Many of us on the board were hoping he would be able to flip his son by signing day but he didn't....nor do I think he really tried. Clint was a HS junior at the time committed to Illinois and NOT a national recruit, only a 3-star. He flipped to Minnesota and as you said, never saw the field before transferring.
