On the fastest over 20m thing, he's come from the American college system and MLS and they are obsessed with the 40 yard timed speed. Quickness over that distance can be influenced greatly through practise and simply doing it a lot. NZ sports don't get too carried away with it and so most players will have developed very little technique to get a quick start etc. This might sound a bit strange but I can vouch for it being true, that's why you hear about how quick some of these behemoths in the NFL are - the American obsession with stats means you need to get good times and other testing results just to get people to look at you. I can give you an example of a guy I was involved in testing for a college gridiron scholarship, he tested really badly, his 40 time was bad and he just couldn't get the start right on the day, he didn't get looked at again, yet he went on to play senior rep rugby for Auckland and Manu Samoa as a loose forward and was widely seen as being quick.
That's an interesting insight, thanks for that. Would you say this is something that we should look at as an ancillary skill for young striker / winger development? It is not a substitute for missing core skills, obviously.
I am speaking from personal experience - for the past 20-odd years most of my tennis wins came from better reaction time than my opponents, but not from better technique, which I neglected somewhat as a result.
The flipside to that, at least in the NFL, is that some really good talent gets overlooked because they don't post 'acceptable' times in these types of drills.
In general, I would say better reaction time is better achieved through better reading of the game and anticipation rather than simple explosiveness (although that helps too).
