Yates as a wasted talent? Why not? If anything it will upset some poms on the board.
There are a few pommy riders I can think of who probably didn't truly reach their potential. Malcolm Elliot, Adrian Timmis, Joey McLoughlin, Sid Barras, Paul Watson, Mark Walsham, Chris Lillywhite.
All had some good results, some even on the continent, but they never really kicked on there. Big fish in a small pond?
