I have to disrespectfully disagree with your basic fighter comparisons... Remember MD you are more the gambler then a fan and or sport writer last we checked.. Which immediately puts you at a disadvantage when discussing these types of match ups with me.. Once again I need to further explain my reasoning to you MD.. Much like a child...
Deeper into the style match up -
First off Oliveira has a completely different fighting style then Stephens... The guys that beat Oliveira do not have similar fighting styles to Jeremy Stephens..
The guys that recently beat Oliveira which were almost 2 YEARS ago (Swanson and Edgar) Swanson a quicker more fluent striker then Stephens, Edgar more of the wrestler then Stephens. Stephens more the slower more predictable come straight forward slugger looking to knock your head off..
Now the guys that recently beat Stephens which are Cub Swanson, Yves Edwards, Donald Cerrone, Anthony Pettis all fast lengthy strikers which are more comparable in style match up too Oliveira.... Oliveira with a tricky submission game too..
Style match up make fights and this match up I believe favors Oliveira... Oliveira is on a 2 fight win streak also.. At 25 years of age he is rounding into a man now.. Oliveira will not stand in the pocket and bang with Lil Heathen one would think..
I can see Oliveira winning this fight by decision or by submission...
