If it was just one isolated incident then yes, Hancock would've been out of order doing what he did. It wasn't though was it, Pedersen has been making reckless moves on riders, including Hancock for years.
Everybody has their breaking point, if it wasn't Greg it would've been anyone of a number of other riders he's rubbed up the wrong way over the years, lets face it, it's quite a list!
Gollob used to knock riders off left, right and centre until a 'quiet word from Boycie' calmed him down.
Judging by the way he cowardly kicked that middle-aged geezer and ran off in Poland, and then a couple of days later starts waving his arm about and retires from a race in Sweden when he's cleanly passed by Laguta, proves in Nicki's case, once a prat...always a prat!
