It's easy to forget that these heavy-hitters in Overeem and Dos Santos are actually well-versed on the mat.
Under the tutelage of the Nogueira brothers, Antonio Rodrigo and Antonio Rogerio, Dos Santos has earned the rank of brown belt—no easy feat for anyone to accomplish, especially under the touted grappling savants whom have submitted some of the best fighters in their respective classes.
Coupled with his stellar takedown defense, "Cigano" has been able to illustrate his striking prowess, which in a way mirrors the similar style of Alistair, who avoids being taken down in order to finish the fight on it's feet.
Though, should he venture to the mat, Overeem has proven that his grappling has improved by leaps and bounds over the years.
In 2005, he became the European Trials winner for the ADCC Submission Wrestling World Championships, submitting all three of his opponents with his head-severing guillotine choke.
In the mixed martial arts realm, Overeem has been able to apply his submission skills seamlessly, submitting the likes of James Thompson, Igor Vovchanchyn and former UFC champ Vitor Belfort—all with his patented guillotine.
Both Dos Santos and Overeem can hold themselves on the ground, though most pundits would believe that this fight will be negated almost entirely on the feet.
