Don't you need to maintain possession for a reasonable time to complete the process of a catch? Cooks is not a runner, to me it’s an Int. As the refs stated, the process of completing the catch never happened, so because the ball never hit the ground it’s anyones ball until someone completes the process of a catch. Just as if a WR catches a ball in the endzone with both toes down and both hands on the ball, but comes down with it bobbling, its not a touchdown. Same thing applies here imo.
