MD Longhorn wroteGood question ... but in my opinion if both call this, and one gives the ejection signal, you eject - if EITHER official sees enough to make that call, go with it.
Seems fine, but let's say the center goes with an ordinary in the act of shooting foul, and give a holding preliminary signal, while the lead gives the intentional (hard) foul preliminary signal?
Let's just say that I'm not a big fan of preliminary signals on double whistles, while still realizing that sometimes one official doesn't hear the other's whistle, doesn't realize it's a double whistle, and gives a strong "sell it" preliminary signal. I hate it when that happens. Luckily, the few times that I've been involved in such a situation, my partner, and I, have both had the same signal, there but for the grace of God ...
