so THATS what that does

I'm playing my first draft day college basketball game with 2019, and I just hit the games portion of my first year. So I'm coaching my first game and of course there's the work ref and yell at ref buttons. I can't help myself, I have to push buttons. So after I get a guy with three fouls in the first 10 minutes I try yell at ref and it looked to me like I got called for a technical or something because they kept control of the ball but I had to try twice to be sure. Lo and behold I got ejected from the first game I ever coached.
But the hilarity of that aside does anybody have any experience/advice for how to handle motivation in time outs during games? Does it even really make a difference? I've actually been floored by the volume of options for what you can do in this game and the coaching screen is no different. But does it actually make any real difference if I motivate? Every combination I've tried so far seems to just result in me being tuned out. In that regards it feels just like talking to my daughter.
