One of them who Mardle believes may not be dominant on the ProTour; but could finally win a big TV title is Michael Smith; he said that he can't keep having chances just to throw them away.
"The one I've been banging on about that keeps getting close and might not necessarily do amazing things on the Pro Tour; but I'm sure Smith will win a big one. He has to win a big one. Whatever it is, whether it's classed as a major or not. You can't be bashing on the door and not smash it down." said Mardle to Sky Sports.
Another player with top talent who Mardle backs to finally fulfil it is Jeffrey de Zwaan; he believes that he is not doing enough at the moment and is on the cusp of becoming an elite player, he just needs a catalyst.
"This may sound brutal but De Zwaan's talent is that of anyone in the top 10 and he continues to underachieve.
He is number 20 in the world by not achieving a lot. I think he is ready to go bang and if he does then maybe these games where he completely loses the plot might disappear. I just think he's got such a great game in him. I wouldn't be surprised if he breaks inside the top 16 or top 12 this year."
Another similar player is Chris Dobey who Mardle admits is a top 10 player; as well that he is better than most currently higher than him; so he believes it could also be a big year for 'Hollywood'.
"He's not under the radar anymore but Dobey is ranked 19 at the moment. He has to be saying to himself 'I have got to be top 10'.
When you look who is in front of him and there's no disrespect to them, but you've got Mensur Suljovic, Joe Cullen, Simon Whitlock and Jonny Clayton. These are not players who are showing better form than him. He can easily match them; as well as James Wade, Ian White and Dave Chisnall."
"He is there or thereabouts is Dobey and I really do believe he can climb the ranks."
