Instant Replay Review in Jets game

Clyde Gates dropped touchdown pass was initially ruled a touchdown by the refs.   The play was reviewed and overturned.  Now while I agree the player dropped the ball I failed to see the video evidence that the ball hit the turf.  How could the refs overturn the call without evidence.  The announcers made no issue of this.  Am I the only one who saw it this way.
