There really isn't that much diff in height man....... Adamek ate some shots against Estrada so he'll prob eat some against Arreola. Although I think Arreola is one of the worst examples of conditioning ever as a pro boxer I think he is going to stop Adamek inside 8 rounds. Adameks best chance is to move for the whole fight, but if he runs out of steam like he did against Estrada he'll get caught more and more.
