I favour Francis to land a bomb early and put Rozenstruik away, round one KO is the most likely outcome. Great insight, I know...
I wouldn't even be that surprised to see Francis bring some sort of grappling or wrestling to the table(Just because Rozenstruik is so weak in this area and Francis has struggled here before so he's likely worked on his grappling and wrestling a fair bit and may want to show what he's got), nothing fancy but enough to at least get Rozenstruik thinking about it and at best end up on top with a messy take down, where I would expect him to finish also.
I very likely wont play Francis though, the line is wide and his round 1 or straight KO price isn't going to be much better, either.
I do see a path for Rozenstruik. He has the cleaner crisper straight shots and seems to land them from nowhere. These straight shots from a fighter that survives a wild first 2 minutes could be a huge weapon.
If Francis goes nuts early and doesn't get the finish he could find himself slightly slower and having to wait to move in agian, then I think he's in trouble. I'm not saying he can't win as the fight goes on, if it does, I just think as the clock counts down so do his chances of landing the big shot.
Rozenstruik we have seen go the distance against an excellent striker, and while he didn't look great and probably lost every round he did remain competitive and he also did have the power right up until the very last few seconds of the last round to finish Overeem.
If Francis is caught coming in with an accurate left hand it could certainly stun him and Rozenstruik could follow up. I don't think he drops Francis dead with one shot but one clean shot could be the start of the end.
Betting strategy.. Potentially a small play on Francis round one KO, if I bet this pre fight at all.. And then look to Rozenstruik live if I feel I see a momentum shift or a tired Francis.
We do have to keep in mind that 2 of Francis' last wins are against completely washed and cooked fighters in Cain and JDS and his only really notable wins are against Blaydes, which I feel was maybe a little early but acceptable stoppage, and Reem - Who Rozenstruik also beat.
I have no doubt Rozenstruik would also flatten Cain and JDS and I believe Blaydes is the only real divider in terms of competition level.
Probably a live bet fight ultimately
