I've just watched both fights and I believe Yan was more dominant. He caught Rivera at the end of the 1st Rd, so that help him in the scorecards. Aljo was unable to outgrapple Rivera, I mean, he wasn't almost able to take him down. So, do you believe Yan would be able to stop Sterling's TDs attempts as Rivera? If he does I believe he out strikes Aljo. Not that Yan is the most technical striker, but he's a relentless one with a good chin and cardio.
