The official called a double T
The other official (the R even though it doesn't matter) came in and questioned the call
The calling official waived off the double T
Personally, I don't think the other official should have said anything, but sometimes it is a matter of survival at this level and that is why the call was changed.
The overtime game yesterday also included an inadvertant whistle. The official granted a timeout when the opposite team had the ball. Lesson learned: always make sure the calling team has the ball or the ball is loose after a made basket.
Also, the intentional technical foul was indeed kicked the day before yesterday. Let's just say the situation was rushed (the calling official has championship experience(s)). When we talk about getting together after a technical foul to make sure we all know what we got, it is very beneficial.
