They're saying Cam needs to work on his professional demeanor and then there's what Yas did. He called him childish, said he acts like he's 12, said he needs to grow up and repeatedly referred to his demeanor when he's pissed off about losing as "pouting", said most of the blame for our 1-3 record falls on Cam, and all of those things are gross exaggerations.
Cam's attitude when he's pissed off about losing isn't pouting. Pouting is throwing a tantrum when you don't get your way, or being petulant when you don't get your way. Cam doesn't hide his emotions well, but that isn't pouting. Sounds to me like Yas is the one pouting about something...
Pouting is NOT throwing a tantrum. Pouting us sitting over in the corner sulking when you don't get your way.
At least know the definition of a word before you challenge some else's use of it.
