1) DJ
2) Phil
3) Kai or Jay
I agree with what Joe McNiel stated, Phil has about two more years and no one will be able to touch him. I have noticed his tricep development is lacking and this is only in comparison to DJ, which is the individual he will have to beat. There is also the factor of muscle maturity and once again the only way to make this comparison is to see DJ and Phil stand side by side, which I had an opportunity to observe.
BTW, DJ and Phil have both never been defeated by Kai, so he is not going to do it this time around.
