If Harrison's complaining to the refs to the point that it is visible to fans, then he is showing them up and it won't bode well for him in temrs of getting a call. I always told kids I coached never to show up a ref, never gesticulate with arms or hands, and if you had something to say, say it quietly and respectfully and if possible, with a smile on your face. Refs are much more likely to listen if you ask them to "watch the push off", or whatever you have to say, if only they can hear it and if it is said without facial expressions or gestures.
I would have to guess he's ganing control of this since he hasn't gotten techs here, but I'm sure in HS, he got a rep for mouthing off, and the refs didn't tolerate it.
