Yes Dave we know what you meant. Early start to this thread but no time to waste !!
This might not help your own personal game game but last year I read good article from Athers about different mindset in improving and specifically when you are in a rut of form and can't find the next run, God knows we've all been there.
He said you can do one of two things
Completely immerse yourself in your own game, technical improvements or changes, where you are totally focuses on scoring more runs or getting more wickets, in order to help your team.
Second....totally forget your own game and work out what the team needs, forget your average which is no good anyway, forget technical issues and work out to help the team do I need to improve certain areas of my game, more strike rotation, developing new shots,more aggressive , or the opposite...does the team need a more defensive batsman...
I found this really interesting way of looking at batting especially.
I still work on technical issues but generally took the latter option, as I'd lost my opening spot in the team.
So for me the answer was yes keep trying to improve technically but mainly look at my weak areas.
The areas needed to work on are still being worked on but it's def helped me and I've become a vital member of the team after being faced with the scrap head.....or the three's !!
The above may not help you but it's a different way of looking at it. Practice is the only way to improve long term, we see it in the Southern nets.....a year on some guys are getting better, thats what it's all about and it's great to see!
