Both are stubborn to their own detriment with the system that they run.
Both have struggled to have meaningful results at high levels.
Marsch's press is his strength and his downfall.
Berhalter's build-up play is his strength and his downfall.
IMO if we are going to pick between the two the difference isn't that great and both wouldn't be the best fit for this US group, with a slight advantage to GGG.
