Ruiz Jr. vs. Knyba: Fight Analysis
This is a hard fight to pick. Ruiz has not fought much. His hand is also a question mark. Knyba is huge and will use his jab. I expect Ruiz to be slow early. He will have to figure out the distance. But Ruiz has amazing hand speed. He is also a smart fighter. He will get inside and land combinations. His experience will be key. If he is in good shape, he will win. Knyba will be tough and last the whole fight. I think Ruiz will win by a clear decision.
The Pick: Andy Ruiz Jr. by late stoppage
