Actually, to be clear, there were two dubious calls. The one where Giannis raked his hand over Theis's groin hard enough to double over the big guy, I thought was a clear foul. I sort of assumed that was what mauf was referring to, but I may be wrong. That was such a clear foul that, you may have noticed, Giannis went over and sat down on the bench initially, I assume thinking he had fouled out.
The one on Smart, I could see calling that either way, honestly. That was a tough one. I'd lean toward a charge on Giannis, but I could see someone arguing that Smart was shuffling his feet late to get out of the restricted area, and Giannis was already off his feet.
