Plays have their progression by design... People think this is street ball, where they just line up and run their routes and Romo looks randomly in whichever direction he thinks a WR is going to be open....
To even think that play was Romo being trivial is just absurd, considering:
1. He called the designed play
2. The play brought the safety into the middle
3. KO got single coverage
4. He put the ball where KO actually touched it
Miles Austin was essentially a decoy on this play and Romo doesn't draw up the plays...
