I agree, it was a great game.
First the interception by Texas at the goal was reviewed and it was changed after the review and the Texans got the ball on the 20.
Next, the knee down or no call doesn`t mean that Texas would have scored anyway. They were stopped more than once.
The play of the game was the stop by Texas on 4th and 1.
Don`t forget I am in Texas, I just hate it when bad calls are made, but that is part of the game and overall the refs in all sports do a dam good job.
