I take it you read the article on Duncan Spencer last month:
https://www.theguardian.com/sport/the-nightwatchman/2016/sep/16/duncan-spencer-cricket-fast-bowler
What a fascinating article.
I'm struggling to remember the guy.
And Dennis Lillee described him as 'frightening'.
Crikey!
It's the same in all sports though, to be first class is amazing in itself, but to play with any kind of consistency at the highest level is something else again.
It never ceases to amuse me how cricket has this gentlemanly, fair play, kind of image, and yet I've always though that to be out there in the middle, bat in hand, facing a pumped up fast bowler, smelling blood, just about to launch something at you that, apart from barely being able to see it at all, if you don't see it, it could easily kill you....is probably one of the most terrifying places to be in the whole of sport.
