Jennings made the grab with two hands, pulling the ball to his chest, and keeping it there as he fell to the ground. Tate had a hand on it. So, Jennings, not Tate, had possession, so "dual possession" does not apply.

The two refs on the scene called touchdown and interception simultaneously. So, even though replay cannot overturn a possession call on the field, there was no clear call on the field.

These refs are atrocious. You are incapable of seeing it because the refs being replaced are in a union, a word that makes you see red. Like the NFL, you seem to be willing to look over nearly anything instead of seeing that, sometimes, union workers are the clearly preferable option.
