Coached? being made aware when people are saying racist stuff about you is completely different from being coached. Smash did not feel discriminated because, he was too ignorant to recognise when he was being discriminated against. I think most people are trying to pretend like this show didn't completely fuck up its depictions of racism in its first season, they were arguably pretty bad and yet I seem to only find words of praise for it lol.
The same issue with when he fought that guy who insulted his sister, I found Coach Taylor and all his other staff members (in a way) all complicit in Smash losing his scholarship. Not only did he not stand up for Smash but he had the audacity to stand up for Mac and publicly announce that he was not going to fire him. I burst out laughing, that man has racial biases he needs to address.
