The problem is...what is "completing the process?" That question isn't just for the vans non-catch. Its for a lot of endzone plays. When does the process stop, especially if a player stays on his feet?
I personally find it ridiculous that if i catch a pass in the endzone, have maintained possession, get 2 feet in, and step out of bounds, its a TD, but if i do the same, yet lose the ball when i hit the ground, its incomplete.
