A receiver who's in the process of going to the ground doesn't have control of the ball until they complete the process of going to the ground and hanging onto the football through the contact of the ground. Dez never had solid footing from the time he landed and his momentum was taking him to the ground therefore he had to hang onto the ball through the contact of the ground and he didn't. The ball came loose upon contacting the ground and he regained control after that. Under the RULE that's a no catch.
You are right that the ball touched the ground. that's about it. Does that mean Dez must still be holding onto the ball, even this minute? No, through contact of the ground...
Contact of the ground has NEVER been defined as lasting beyond an elbow or knee down. NEVER.
THEREFORE, when Dez's right elbow was down, the play was OVER! The fact that the ball came out later never mattered.
"Under the Rule" means... KJJ has no idea what contact with the ground means. You just listen to Blandino's comedic interpretation of it is. The phrase doesn't mean anything more than knee or elbow down.
What if Dez had fallen to the ground in the EXACT same fashion, except he hit with his right knee, right hand, and his body momentum stopped, then he stood up, and walked into the end zone? Would the cheat BLANDINO expect the rest of his body to hit the ground, for it to be a catch? No, every official would call Dez down, right where the ball was when his knee or elbow hit.
So, in this loose interpretation of an undefined phrase,
now, players can have a knee or elbow down, unable to advance the ball any further, but the catch is still in question?
That concept HAS NEVER BEEN defined in the rule book.
Calling Dez down the instant his elbow hit is what should have been applied against Green Bay.
The rule doesn't establish a new standard of what contacting the ground means, no, it just lets Blandino talk a bunch of nonsense so that referees can arbitrarily apply rules to take away catches, even in pivotal playoff games.
