It did more than just shift in Dez’s hand, it popped out. If you watch the long run reverse angle shot you can see he’s flipping over and the ball is in the air, not touching him at all. That’s clearly a loss of control. If it had been a catch that’s a fumble.
No one will answer my questions about the other possession booth review, and why they should be different. I contend they should have been the same - both complete or both incomplete.
