I've said it on Campbell threads before, but his sideline behavior often results in him being distracted for multiple plays. After one play yesterday, he screamed, "Fuck you! That's fucking bullshit." About one of the plays. The side judge warned him.
Even when there are shitty calls, you have to move on. Campbell complains about something every play, so most of the time he is wrong. Probably part of his "us against the world" or underdog mindset. Or he's just an incessant jackass douche.
This board will sometimes complain about Sark's sideline demeanor after shitty calls, but he realizes that it is largely outside of his control and he does not let it affect him - or the team - beyond the play in question (if at all).
Last night, Sark was frustrated with how long it took for the side judge (I think) to get his timeout call - on a play that we also got flagged for false start (waived off). He said, "you need to do your job; that's your job" or something like that. He did not swear at the ref. He did not lose his mind.
