Here is a link to a previous non-catch that was equally as consequential. Megaton, caught a TD, went to the ground and left the ball there. Incomplete pass.
Beat me to it.

You're right. I learned that rule over night. The possession rule is DIFFERENT for a runner with the ball and a receiver who catches a ball.
The rule needs to be changed........... because the Steeler receiver plainly caught and controlled that ball before his knee hit the ground, then he reached over the goal line, slightly losing control of the ball.
Oh well........... it's over, it's nearly 2:00a.m., and they'll all play another day.
