I get and agree with the logic behind the rule but wow, what a stuff up. Players and fans are baffled.
It doesn’t have to become a complex issue to interpret and manage. Keep it simple!
If a player expresses verbal dissent, ping him. That’s pretty simple.
If its not verbal (eg shaking his head in frustration, etc), umpires get real, it should not be considered disrespectful. The player can only be considered to be respectfully expressing his frustration at either himself for stuffing up or on a decision that has been made that he disagrees with. What the hell is wrong or offensive with that?
Get real!…… and GO DEES!!!
