I disagree with you, Jrry. The receiver should just hold on to the ball in the first place. If the rule is changed, you now have to distinguish between a fumble or incomplete pass on bang-bang plays, and I think that call is a tougher one for the refs to make. This rule is not hard to understand, just hold onto the don't let it move when it hits the ground.
The rule isn't hard to understand until you see it in action. And then you have a lot of nonsensical rulings where a guy clearly caught the ball and made a move to score but ends up with an incomplete pass, like today.
I think it's stupid that you're going to ask a receiver who has caught the ball to pass up a TD or first down conversion in order to avoid overturning a stupid rule. It's not a hard call to make. It's an easy call to make. Did he get his feet down? If yes, did he make a football move? If yes, it's a catch. Did the ball get into the end-zone? If yes, it's a TD. If no, was he down by contact when it got knocked out? If no, that's a fumble.
It's very simple, and it would prevent the asinine results that end up with people pissed off because a clear catch was turned into an incomplete pass.
It's easy to sit here and say, "Hold onto the ball." But you're not the NFL player catching the ball in the final seconds who is trying to make sure he gets into the end-zone instead of touched down at the one yard-line.
P.S. You already have to distinguish between a fumble and an incomplete pass.
