Comes down entirely to how the first five minutes goes. This feels like Edmen's last chance to show that his fundamental problems have been solved in regards to conditioning & grappling. They've given him Gerald who excels in those two fields... but is otherwise a pretty middling fighter who's slow & unathletic as can be, a mediocre wrestler, and not a particularly great striker.
Edmen stands a very good chance at just blitzing Gerald while he's still "cold" in the first round and putting him to sleep with hard, fast shots. Edmen is remarkably dangerous in the first round and we've seen Gerald get caught and put down early on multiple occasions. However... if he fails to put GM3 away cleanly, I think we'll probably just see another fight where Edmen inevitably gasses out and ends up getting kicked in the ribs by a bloodied Meerschaert who inevitably scrambles onto his back and chokes him out in the third round.
I might pick Shahbazyan based on the early danger he presents and because at his age he should have more potential for improvement (not to mention he has been competitive with better fighters who were even more of stylistic nightmares, a la Fluffy)... but not with any real degree of confidence.
