I think your wrong on both accounts. Jr. isn't getting any flashy KO on adameks cheen. And with that glass jaw that jones owns, it wouldn't be long 'til Adamek shatters it. This one isn't too difficult to figure out.
At HW, probably RJ. I think Adamek would give RJ a much better fight at LHW, but Adamek looks so limited at HW. Arreola was battering him from ring post to ring post and Adamek was getting rocked with every punch, but he always had a "cheen" and alot of fighting heart. RJ still looked like the SMW version of himself, except without too much power either, where Adamek looked very clumsy and on wobbly legs. I think RJ just too fast for Adamek and would win a decision.
I love both fighters but Jones would be my pick here by UD. Ruiz did catch Jones with flush shots and Jones took them well, it won't be easy for Adamek to land enough here.
Adamek got schooled pretty badly by Dawson. Now, Dawson and RJJ aint exactly clones of each other, but I think you can say that speed and angles are bad for Adamek. I think RJJ would be the absolute wrong style for Adamek, who would have a frustrating night - and ultimately a lopsided loss.
