JDS, Hunt and Overeem are the best HW strikers in the world. Cain and Cormier are arguably the best wrestlers at HW but Cain is still young and is constantly improving all the time.
The MMA world will definetly see an improved Cain against JDS because of potential and athleticism. For me JDS has also improved but not at the level of Cain who is still learning at a rapid rate and destroying every opponent except his JDS loss.
Cains boxing technique is actually great offensively but Im sure he has trained extensively on his defence which is paramount against JDS.
