If I remember correctly, Grobe not redshirting Lee was ridiculous. He essentially only played special teams his freshman year, which was Grobe's last year and Wake was awful. Back before the 4 game redshirt rule, playing a true freshmen on only special teams, especially on a bad team, was incredibly short sighted and looks even worse with a coach on his way out.
He would have been a huge contributor in 2017 (Belk Bowl, Wolford's last year) as a RS Senior. Although there is a chance he would not have returned for that year (he was 1st team All ACC in 2016 and ended up as a 5th round NFL pick), I really think he should have had that option available to him.
