Mitchell is a 6'8 PF that only played ONE ranked team last year (Creighton, lol). Against those college teams, most of which ranked in the 200's (literally), he shot 44% from the field and 30% from 3. All his numbers went down from the year prior. He either fouled out or only had one more foul to give in nearly half of the games last year.
He has talent, but all of that above is a definite red flag(s).
People have bad games.. but does this 'look' like an NBA PF?
Against Florida International (lol) - 32 minutes, 0pts, 2rbs, 4PF's
Against LA-Lafayette (lolololol) - 25 minutes, 3pts, 4rbs, fouled out
In the Florida Int'l game he was guarding Tyrnell Murphy who put up 22pts and 2rbs.
In the LA-Lafayette game, Mitchell was guarding Shawn Long (mostly) who put up 23pts and 15rbs.
