If Brown is truly getting on Keegan for not shooting Brown's wrong. Chet was about to swat that into the upper deck. Nothing wrong with getting to the rack.
It would drive me nuts if I felt like if I didn't make a tiny move the way someone watching would have me do, that I get yanked. It would make me feel like they thought I was stupid and not capable of figuring it out on my own.
This can happen to soft spoken people. Outsiders or people in a mentor role view it as an opportunity to micromanage and provide "leadership". It's insulting. Keegan has earned a WAY longer leash than Brown has him on.
