Good point Brad.  I was sitting in the West stand in line with the 18 yard line.  I saw Derbyshire grab the ball, and then Green look at the bench and point to himself as if to question with the boss whether he should be taking it.  When Derbyshire missed it Green was the first (as far as I could see only) player to go to Derbyshire and he clearly gave him some genuine 'don't worry, head up' encouragement.  I might have misread it but it looked like all of the above from where I was.  We were probably that stunned to get a penalty that it took us by surprise.
