If you go by the numbers, then Neil Robinson’s influence on para table tennis in Wales is easy to recognise.
Of the 11 Great Britain squad members off to Paris in August for the Paralympic Games, four of them are Welsh.
That’s 36 per cent of the squad. Not bad for a country that represents only five per cent of the UK population.
But there is far more to Robinson’s impact as one of the national coaches for British Para Table Tennis than just the inclusion of Rob Davies, Paul Karabardak, Tom Matthews and Josh Stacey for the Games this summer.
You have to produce fertile soil if you want anything to grow. So, more significant than a snapshot of current success is the coaching environment that Robinson - the former Paralympic gold medalist from Bridgend – has created at his Sport Wales base in Cardiff.
Not that all Robinson’s time and efforts are focused on producing elite athletes. When he’s not busy honing the next batch of Paralympians, he can often be found at the University Hospital, Llandough, encouraging those with spinal injuries to discover that sport can still be part of their lives.
