On the long catch by Austin, it wasn't clear to me that the ball hit the ground. He had it in his hands. The ball bounced upward when Austin hit the ground, but did the ball hit the ground or was it a result of his hands hitting the ground? I couldn't tell, but it was reviewed correctly since there apparently wasn't sufficient evidence to overturn it. I would be the last person to go out of my way to defend Fisher, but it is possible that, from his vantage point down on the field, he could see that the ball didn't touch the ground. If so, I can't blame him for challenging it since he may have hoped that one of the cameras would show what he saw.
