Could and probably should have been worse because I'm pretty sure just before the missed FG they had a legit TD denied (looked legit to me because it looked like their receiver had control and one knee down in the endzone).
The guys on TV seemed to be sold it was a TD but the ball definitely moved not just once but twice.
They focused on his knee being down (equaling two feet) but the ball moved both before and after that I believe. I think had they called it a TD they probably would have upheld it, but since they called it incomplete there may not have been 100% enough evidence to overturn it.
I originally thought it was a TD too but when you watch it, the ball def moves.
