He will realistically get what, a 5 year window without the current top 4 dominating? If we assume he doesnt get exponentially better and there are no serious up and comers that dominate at an early age (come on Pewilo!) He could very realistically win a handful but I mean, its not like he is losing to the top 5 in slams now. Hes losing to people who are equal or worse.
Also there is a polish guy in his age group who could very well out pace him (could argue he is nearly there) in progress if he can get his temper under control
