The punditry/commentary curse strikes again. Every player, bar Ronnie, has pretty much fallen apart after starting their media career before retiring from playing.
It obviously impacts on your playing career, both through lack of practice and the comfort zone aspect of commentary and punditry, so I don't know why a still relatively good player like Smurph is trying to juggle both.
At least when other players started their media careers, with the possible exception of Hendry, they had little hope of winning any rankers anymore. Smurph has proved he can still compete in rankers though, plus nobody likes hearing him four frames in a row!
