Hold your cards close to your cheast!

Graham Henry had some of his set piece strike moves broadcasted to the world thanks to some photographer that through ethics out the window....
With technology heading forward at a rate of knots even at school or club level it is very easy to video tape a game and know the oppositions tactics (generally at this level most teams might have 1 or 2 patterns of play).
Important thing is I think at Club and school level that you don't get too sidetracked with the oppositions strengths and panic. A team I'm assistant coach of has a semi this weekend and our head coach is in a panic as the opposition has a strong and experienced tight 5 and we are missing a few key starting props due to injury etc. The stress of their strength is getting on top of him to a point where he is forgetting that although they have a strong and experienced tight 5 they are unfit and play a 1 dimensional style of Rugby with pick and go's and runners off 9. We have an outstanding backline and a far more mobile forward pack, this to me negates their tight 5 and just means we need to focus on our strengths and be confident as far as a team profile we have a better one than the opposition!
I'm sure Graham Henry is deep down a little ticked off with his tactics being exposed but if he focused on this and didn't move on and adapt he wouldn't be doing his job as coach of the All Blacks! My point being - Hold your cards close to your cheast but if your cards are telegraphed to the opposition don't dwell on it, adapt and move on!
