I hate that the rule took away a great catch in a clutch moment of a critical game. How much more "big time" can you get? To have that taken away by the niggles of a convoluted rule is sad. I hate it for Dez Bryant. Per the rule, however, I agree that the correct call was made.
I think what needs to be done is to further specify what is a "football move". What if I catch it flat footed, stand still for 5 seconds, then fall over and use to ball in one hand to cushion my fall (a la Calvin Johnson)? By rule, I am not sure that's a catch. I haven't made a football move of any sort, but I clearly held onto the ball for a substantial amount of time. Athletes today are so awesome that they can catch the ball, get feet down, and make a move (like lean, stretch, twist, etc) in a split second. I think the "football move" thing is the part that needs work... or maybe have another way stated in the rule book to consider control of the ball to be established.
