Anytime a ball is on the ground, players are diving after it. Even after obvious incompletions. Why? The refs occasionally screw up and call them fumbles. The players are doing what they were coached to do because the refs sometimes call it wrong. I wouldn't base the ruling/call on the players' reactions.
I'm not. You completely took my statement out of context. I was saying that the ref had no reason to be focusing on JT's throwing motion in that play. He dropped the ball suddenly. So, if the ref wasn't focusing on that exact issue (how could he have been?) how do you, as the ref, react when you suddenly realize the ball is on the ground? Would you blow your whistle in the first 1 or 2 seconds after the ball is loose & when there's no clear possession? Personally, I wouldn't.
In hindsight, it's probably the wrong call. And yes, my reasoning probably gives rise to a conservative bias. But at the end of the day, it's not a bias towards a specific team (btw, thwg). It's a bias towards human reality. And on review, it's not an indisputable call, as you can see from the disagreement in this thread. therefore, even though it's the wrong call, it's correct call. If you don't like the call, don't fumble/unintentionally spike the ball on 3rd down with 2 minutes left near midfield when you have a 4 point lead and are playing in front of 90,000 fans on the road.
