When Kevrone was on, he beat all the rest, but Shawn was good all the time, consistent as you said.
But when Kev was on, he was Great.
If we measure physique in 1-10 (where 1 is very bad and 10 is very good).
If Shawn always was around 8, early Flex would be around 9 and at a later stage at 6-7, while, when Kev was on, he was at 10.
Palumbo hovering around 1-2.
