Velasaquez and Overeem will likely fight for the heavyweight championship later this year. There only common opponent is found in Brock Lesnar. Both of them have first round KO's over the former champ. My question is: who's do you think was more impressive? Personally I'm going to go with Overeem simply because he was the only one Lesnar has not been able to take down in addition to the fact that he controlled the fight entirely with more impressive striking.
