Was ED's catch a touchdown? He clearly 'caught' the ball, but dropped it out of bounds after scoring.
The explanation I've heard is that you have to 'complete the catch'. It's unclear to me though for how long you must maintain possession after going out of bounds. Isn't it a touchdown as soon as you break the plane of the goal line?
What if he doesn't drop it right there, but stands up out of bounds and then drops it. Is that incomplete?
Discuss.
