Ohio State, Ryan Day befuddled over critical calls in Fiesta Bowl loss to Clemson

That article deals with balls on the sideline or balls thrown into the end zone. In the ohio case, the ball was caught outside the end zone, then carried into the end zone, then the ball hits the ground. It's like a running back crossing the plain and then having the ground cause a fumble. Once the ball crosses the end zone it's a touchdown.
So, your article doesn't account for this situation.

Its nothing like a running back carrying the ball. Thats why you cant understand it. The catch has to be completed. Crossing the goal line with an unsecured,thus uncaught, ball means nothing. If a running back crossed the line bobbling the ball and then dropped it before securing it, it would not be a TD unless he dove on it or picked it up and secured it. ( Thats a totally different rule)

The catch was completed. One foot was on the ground before crossing the goal line. The ball crossed the goal line. Touchdown.

You are clueless about the current catch completion rules. A foot on the ground does not constitute a "football move." The foot establishes point of possession, not possession. NCAA rulebook is available online. It would benefit you to read it.
