I wouldn't call him a coward, but I maintain it was a gutless display. I don't think that is a personal attack. As I said, I think he has been pretty unfairly treated throughout his career bowling wise, but it is just incredibly frustrating when a guy who I know can bat does that. Same reason I get frustrated with Southee getting out slogging in a lot of situations - it is clear he has more ability than that.
I agree. He can be the nicest guy imaginable but as you said before it's the symbolic nature of the surrender that makes it humiliating and in a subtle way damaging to team morale.
I was thinking about Ewan Chatfield today, an awful batsman, but one who always tried to sell his wicket dearly, even after nearly being killed by a bouncer in the 70s. His innings back in '85 when he and Coney put on 50 for the last wicket against the Pakistan quicks to win the test was an example of the kind of determination which seems to be sadly lacking nowadays.
edit: not technically the last wicket of course, but since Cairns had to retire hurt concussed by a bouncer it made Chatfield's effort all the braver!
