I think that is a little unfair on Marco!!! Ranking event winner - been at the top for a long time.
Nobody on this thread has mentioned the apprenticeship, so to speak, that needs to be served to get to the top. Less than a handful have gone straight to the top of the game. It takes a long time to learn how to play the game properly. Alex and Corey have had next to zero exposure to this level of play. Although there maybe some good players in Canada, the standard of the top players there from what I can see is the same as decent club players from the UK, nothing more. And it is even weaker in the USA. I don't mean any offense by this.
Chris Melling has been here before trying to qualify for pro tour. He know the score. He could have a chance of qualifying if he has been knuckling down on the snooker table - but not sure how much he has committed himself this time. He has always tried to juggle E8B, snooker, American pool and never given one of them his undivided attention fro more than a year at a time. It speaks volumes for how talented the guy is that he has been a multiple winner in pro E8B and American pool whilst still attempting to get on the snooker tour. His fundamentals, when it comes to approaching a snooker table, are twice as strong as Alex's and double that again for Deuel. If Chris can't do it - I don't hold out much hope for the other guys.
You cannot fault them for giving it a go though, fair play to them. Takes nuts to take on a task like this - especially going in blind.
