For me the issue when it is most painful to watch is less structured play (like the pictured where we are set up) and more mid tackle count when a ball goes short side or something and the people outside are flat footed.
Sometimes a little deep probably thinking about setting up something later, or missing the start and not catching up before someone (often Nicho) has to die with it*
In plays like above they need to time their run off the play the ball and the halves speed which should be easy enough to get right most of the time given consistency of practice. But with high level wrestle if you are the winger and trying to start your sprint to time to be in right spot at full pace at right moment, that probably can be a bit tricky at times.
* I think Nicho also likes to challenge to his side and just take the tackle if there is nothing that opens up, I think a lot of other halves would make the pass to someone even though they know it's not on, because they are supposed to pass and other people are supposed to be tackled.
He keeps better field position and draws in future defenders by going himself
