Under today's conditions, he would dominate much in the same way Ronnie did.
Looking at it from a different perspective, if Jay and Phil were to go back in time to Sergio's era, do you think they would look like this?

oh thats a much better way to look at it TL...
i think jay yes its possible, bc he trains seriously and proved for years, never really taking time off.. takes diet serious, hes a real bbr. he could stand with serg
other hand phil, i think has a great build unique, arms obv make him...
however,,, how many years does he have in the gym, really.
then it comes to quality of time... nice way to put it no i dont think he would take serg or even close.
i think kai beats phil in these regards bc at least how it "seems" with kais deeper mentality & seriousness about training, .
again nothing toward phil hes obv doing right i just think hes still green re gymtime served compared to others.
i think ronnie would have beaten serge back then.
