I don't think they have gone cowardly at all. Granted I'm Aussie so I'm probably biased.
I think for the first few tests our tail has been quite long, Ollie Robinson was right there. I also think Murphy is not up to it yet and would get targeted. Again, I really though the conditions and England's aggression would have been good for Boland, but he doesn't appear to be anywhere near as accurate as he has been.
Starc whilst getting wickets is bowling a lot of puss and I'm only ok with him as the left armer is good to have.
Look I think this Bazball visionary stuff is a little over blown. I just call it good aggressive cricket played to the individual players style, which is great I just don't think its revolutionary. I think Australia's approach has been fine in terms of their batting, it would be folly to try to play like England do. I do think the short, pitched half trackers bowling we have done up to know is pants on head stupid.
Loved Woods bowling, Stokes is one of test crickets most cleanest hitting batsman Head and Kawahja have been gritty as hell, Cummins is bowling well, but gee the Aussies need to pitch the ball up more.
I don't think the declaration in the first test lost England the match, it was the second innings batting.
