Judge is fine.
When was the last time you saw a big in college who was soft as a sophomore but grew balls by his senior year?
I'll answer for you, somewhere between extremely rare and never. Toughness and killer instinct is something that comes early if you have it. Someone cannot make you tougher by yelling at you or just wanting really badly for you to nut up. Wally will become a better player, he will never be a JYC.
