No he didn't,
he kept trying all game and was well rewarded in the end
Sorry from what I saw, there were a few times where when things went against him he stopped, propped and refused to chase, refused to give a 2nd effort, to me that's dropping your head
In the 2nd qtr in particular I can remember at least 3 or 4 occasions when he did that
2nd half he was better, didn't do it but in the first he certainly did
