#2 Brock Lesnar doesn't lose most of the matches he's in
The reason why Brock Lesnar is still a proven draw after so many years is that he hardly ever loses. That's why it's hardly a surprise that he defeated four other competitors to become the WWE Champion.
A win was necessary on such a big stage especially after the loss to Roman Reigns in Saudi Arabia. One has to believe if Roman Reigns vs. Brock Lesnar was happening, the outcome would have been pretty much the same.
#1 Brock Lesnar vs. The New Day is a story yet to be explored
