The 2 biggest areas of improvement I want to see are in defence
1) I will really lose my **** if we once again leave huge gaps on the outside and let the Welsh breeze through because the defence can't be bothered to drift across and cover it. Leaving a gap on the wings is fine but the defence MUST ******* drift across when the ball starts going that way. If the players simply aren't going to put the effort in to doing that, they either need to be dropped or the system needs changing.
2) We also need to stop the situation where a player can run at a shoulder and neither player seems to bother making a tackle, like they each think it's for the other guy to do. You can't spend all your time worrying about covering off the offload if you aren't making an effort to tackle the guy in the first place.
To a lesser degree I want us to stop the bullshit of under-resourcing rucks, it doesn't matter how nicely spread out in pods your players are if the ball gets stuck at the bottom and you end up just doing a 1 out pass anyway. Lastly, it's so annoying seeing a player make a break and nobody else can be arsed to move at anything below a slow jog to support them, get your ******* arse in gear and get on their shoulder.
Fundamentally a lot of it comes across as the players being lazy and, when given the option between putting in extra effort to assist the team or trudging along to the next pre-planned move, they nearly always opt for the latter. We are probably one of the worst teams in the world for refusing to take advantage of a situation if it means putting in a little more effort or deviating slightly from the norm.
Just clean up the basics, put in a solid defensive shift and show control in attack and that will be just fine for now.
