This is exactly my problem with people who point that the fouls ended up being pretty close so we can't blame officiating, especially when they weren't even watching the game.
You have to call it both ways.
I'm fine with what Collins did being a technical. Just a couple plays before that Millsap was way more demonstrative at an official and he didn't get a technical. There were at least 6 other times where Jokic, Craig, Harris, and Millsap did more than what Collins did there and Foster ignored them. There was even a timeout where Jokic had to go half way across the court out of his way and was pointing and yelling at one of the officials and he didn't get anything for that.
This happened with fouls too. There was a play where Kanter got fouled 3 times in about 4 seconds by Jokic with no call. Denver comes down and they call a touch foul on Kanter when he didn't even make contact with Millsap. I'm fine with the foul call IF it is also called on the other end. There were several foul calls that if Jokic was held to the same standards for fouling he would foul out in less than 5 minutes every game.
It's either a technical or it's not. It's either a foul or it's not. Refs need to be called out for their blatant inconsistency.
