Yes and yes. I also understand virology. At the most basic level, you can't transmit a virus to someone if you don't have that virus in your system. You also can't transmit a virus to someone if you had it at one point but it's no longer in your system. His daughter wasn't going to be with him for the playoffs. So how is she at risk? With the amount of testing and monitoring that will be going on, there's almost no chance he's going to return home with the virus and not know about it. If he wanted to be extra safe, he could self isolate for a week or two and get a couple of extra tests after he wins the cup. It's statistically impossible that he would get his daughter sick after all that.
The silly thing about all of this is there would be far more of a stigma if he had just come out and said he was worried about his personal health even though that is a legitimate risk, but hockey players are warriors and aren't allowed to have thoughts like that.

As a doctor, I can tell you this is completely wrong.
You actually don't have to have the virus to transmit it. Although it's small and the CDC has basically said that transmission through surfaces is small, it still exists. So yes, you can transmit it without having it...via object and surfaces, clothes, etc. Plus there's so much we don't know about COVID yet. The reality is that his daughter may be immunocompromised and at higher risk...we don't know what transpired from her previous respiratory viral infection....maybe it was just a severe common cold...but I'm sure if it was serious, and if you had kids, then you would understand.
As for exposure to his family, aren't families also coming? Wasn't that the whole point of selling the mountains because their families would be potentially staying in Banff/Jasper and for players to get to see their loved ones between games as an extension of the bubble? This one isn't really known yet, bunch of logistical details are still being hammered out.
