Steve is without a doubt a hugely talented rider, he's averaged 8 in the PL in the past so of course he can do it. If he settles down and gets on with the job at hand he can get 8 again. His issue is he tends to go AWOL (litterally!) and bad stuff happens. You're right, he could be one of the leagues top men, throw in that Kennett will be and Garrity should be and the Rockets could have a formidable team.
TBF the Aussies do tend to be a little less PC than us.
