Just about all of the MDL teams, including those attached to senior teams, were run by 'enthusiasts' in my experience (which was 10 years ago now). I don't think that I came across the person you refer to: just about all of of the riders I saw were young hopefuls. People on this forum are always moaning about the shortage of riders, but IMO the destruction of the MDL has only contributed to this. Provide the opportunities and the riders will turn up.
