I expected as much, but I saw several others also posted after the tip-off so I went ahead posted as I hadn't even turned the TV on yet, and it looks like their predictions were used.
What is the official allowable late length of time to be counted?
As much as possible, I try to go by actual tip off not scheduled tip off. I believe in that game, the tip-off was roughly 6:33 (mountain time) and ripcityboy posted at 6:34. I generally give a minute or so for stragglers. However, at roughly 20 minutes late, can't allow.
