I personally don't see a need to use the catch signal or the bobble signal. The communication is very simple and direct. If the pass is incomplete then you give the incomplete signal. If it is complete you mark the spot and indicate the down if it is short of a first down and if it is a first down then you wind the clock and then stop the clock and indicate a first down.

How dumb would this look? A pass is thrown into the endzone that is close to the sideline. The receiver goes up and catches the pass and comes down with one foot in. It's a touchdown. You signal that it was a catch by using the catch signal and then you throw up the touchdown signal. I don't think so.
