Questioning why Paige was in the game at that point is not valid. Why was she in the game at any point, the injury could have happened anytime, including practice. So, why make Geno the scapegoat. Why not pull her out a halftime, if you have a big lead. Paige wants to play basketball, not sit the bench every time they have a lead. If you ever played sports, you would understand that.
This is why the criticism continues. It absolutely is valid. Coaches clear their bench at the end of games for a number of reasons. One of which is to reward players who also want to play. Another is to prevent an injury to key players. To follow up that nonsensical "not valid" statement with "if you ever played sports....". You've got a lot of gumption for someone making an argument i'd expect from a 7 year old.
The argument is devoid of any critical thinking. The game wasn't decided at "half time". The game wasn't decided "at anytime". The game was most certainly decided when she got hurt. He should pull his starters out and play his bench more (but not exclusively) when he has a big lead at halftime. It helps mitigate the risk of injury to the starters, and gives the bench some much needed experience. If Geno chooses not to, that's his choice, but we're free to criticize the logic, rationale, and outcomes of those decisions.
Of course Paige wants to play.
Every woman on that team wants to play. If you ever played sports you would understand that.
Followed to it's logical conclusion, your argument is basically "anything can happen at anytime, therefore nobody is at fault for anything". It's silly and devoid of logic and reason.
There is risk associated with virtually every single decision we make in our lives. We calculate the risk and make a decision. Practice is a calculated risk. Sure the players can get hurt, but without practice there is no improvement to the individuals or the team. So you take precautions. You stretch, warmup, cool down, recover. You manage the risk. When you're up 20 with a minute or two left on the clock, you manage and mitigate the risk. Geno decided playing Paige was more important than mitigating the risk and unfortunately for Paige and the team, that decision backfired.
That's all there is to it.
