It's a bit hard for me to do the comparison, as the game has developed a lot more, and there are so many new technicalities to consider especially for Wingers.
Based on their physical attributes, they are both monsters! I just wonder if Lomu were to play now, would he have lost a few more kg's, have a bit more leaner body and maybe even a little bit faster?
If any of you have seen the training that Lomu did when he was playing, it's something not a lot of guy can do. Doing Squats with each leg on a different gym ball while squatting with a bar of weights above your head is something to admire. I don't think Savea has that in him, but I stand corrected.
