All the "experienced officials" here have a sound philosophy on this one, IMO. I guess that's why I posted this sitch.
If any of those here had posted what I posted...I would have probably said the basic same things you vets stated.
For some reason that night...my partner (T) and I (C), big-timed the L. I don't think I have ever changed a partner's call like that. The weird thing about it is...my other partner T, was doing the same thing.
The only redeeming thing is...that the L put up his FIST for a FOUL. We gave him a chance to "keep" his original call.
It's lame...but, the only thing I can think of whithout beating my egotistical self up for.
