I haven't seen Pudilova make very much improvements at all since her first fight. She trains out of a no-name gym in the Czech republic where she is the biggest name. Her defense hasn't really improved. In her last fight she tried some head movement when her opponent wasn't even in striking range but when she got bum rushed by Sarah Moras of all people, she got tagged and hurt. Against Kim, she got countered so badly in the first 2 rounds that she complained in between rounds about how she couldn't strike with Kim and proceeded to wall and stall her way to a non-deserved win (Kim clearly won the first 2 rounds IMO).
The biggest problem for Pudilova in this fight is her lack of power and physicality. Once Kim realized that she could just walk through Pudilova's soft punches, she really dominated the striking. Pudilova was outclinched and outgrappled by Lansberg early, was 50/50 clinching with Kim, and lost Rd1 on bottom to Mroas (and could've lost Rd3 too IMO). We saw how strong Aldan was outwrestling and overpowering Bernardo in her last fight, so I think that Pudilova trying to grapple would just tire her out.
This is a pretty even fight but with Aldana's power and her physicality, whatever she does might make more of an impact in the judge's eyes. So I liked Aldana as a slight underdog, and also liked her +155 decision line.
