I think it's a good point. I've often found that I come in when batting low down the order and we are chasing a total, so the ability to select your shot and defend the people below you becomes paramount.
I'm a terrible tailender in respect to scoring runs quickly with only a few balls to face. I'd rather build an innings than come in with two overs to go and have a slog. That's just me though.
this is true sometimes u get the reputation that your just a tail ender when sometimes you have worked hard to improve your batting but you will never be given the chance to prove other than at nets but I think once you are classed as a "tailender" its really hard to get out of. and when you do get a chance in a game it always like last 5 overs or something or your teams 60-8 on a minefield.
But also what i was getting at was to do with shot selection even batting up the order its one of the most important things u can have an amazing technique and eye but with out decent shot selection u will most of the time fail except those rare days when you seem to turn up and you seem to be blazing every shot and everything flying over the ropes. but this is difficult for tail enders because you dont get much time in the middle to practise this.
