Whether or not people consider it dirty or not by Scott, how anyone can say the referee got it right is just astonishing. Scott pushed Chris, avoidable or not, and Chris went down so Scott should have been excluded, simple as that.
Those who say Chris could have stayed on and finished really are being pretty stupid. If by stay on you mean completely give up on the race and trot round behind the guy who just took him out then why should he? No rider would, or should, do that, he got took out by Scott plain and simple.
You can argue over any malicious intent by Scott or not as only he will know but to say the referee got it right is absolute nonsence.
Every rider has their riding styles, that's just they way they are, settling for second is an asset not present in world champions of any sport I'm sure.
Do you mean world title? It's that riding style which won him a GP in his first year on the circuit, in front of his home crowd, something we've missed for a while.
