Umpires always vary on how much they'll listen to before taking action. I don't know if NCAA has a rule requiring a warning before an ejection, though.When did they start giving warnings for that? I noticed it last night with Lemonis too. I thought arguing balls & strikes was an automatic ejection by rule.
As a little league umpire, I usually have a long leash for simple argumentative comments, but if the coach comes out of the dugout to yell about balls and strikes, I'm not bothering with a warning.
