Where's the evidence for this?
I hate to pour cold water on the celebrations but regardless of your sport, the greatest performers make notoriously poor managers. I'd say the jury is out on Screeny as a manager. Come back at the end of his first season and then make a judgement about whether this was a good move or not. My guess is that Joe will still be too in touch with his instincts as a rider to fully assimilate the finer intricacies of man-management, team dynamics, off-track politics and polishing the egos of pit-stop prima donnas which his new role will demand.
I wish Joe every success in his managerial career, but perhaps this is one chicken we shouldn't be counting until it's fully hatched. Nevertheless, it represents a bold move by the new promotion and demonstrates they're thinking big and are ready to take a punt on untried potential.
