Khalil Rountree vs. Marcin Prachnio is an interesting one.
The odds favour Khalil to get a 1st round KO. However, it should be clear to anyone who has followed Rountree that he is absolutely terrified of fighting (not passing judgment, just a factual statement). Being violently brutalised by Cutelaba is likely to increase his anxiety. Consequently, if allowed, I would expect Khalil to be very happy to replicate his performance against Eryk Anders–winning the fight with ease, but avoiding the risks involved in hunting a finish.
The question is if Prachnio will allow that fight. Against Sam Alvey his mindset was kill or be killed (and killed he was). But even Alvey was willing to bite down and take one or two to find a finish, something I would not expect from Khalil. Against Ankalaev and Rodriguez, Prachnio looked way less confident, and was hunted down rather than bringing the fight to them. Considering Rountrees "flakiness", overwhelming him with aggression early would probably be a good game plan. But my bet is that being knocked out in three straight will make Prachnio a bit cautious.
Not being sure about Prachnio's cardio I was tempted to play the o1.5 at +150. But if the fight goes anything like I expect it to, it will be slow paced enough where he should be able to last three rounds. My bet is Khalil by Dec @+650 (!).
