Honestly, I’d take an average Tai Tuivasa fight over a Rozenstruik 5 round jabfest any day of the week.
Rozenstruik just can't win, lol. Back in the day hee didn't utilize his jab as much as he should have and he instead sat on the back foot, waiting to kill dudes with that one perfect shot. Zero output, led to some boring fights where he got outhustled, but every once in a while he would explode out of nowhere like Romero and murder someone while behind: Reem, Sakai, etc.
He recognized the deficiencies in his style and made efforts to try and improve by becoming a rangy distance striker who can still counter-strike, but is more willing to fill the in-betweens by going first with kicks and, yes, jabs. He landed a pretty crazy number of significant strikes on Gaziev and Tuivasa and showed actual improvements to his game... which is rare for an old Heavyweight who came from a different combat sport. He's still not a great fighter, but I like seeing that personally (especially in a talent-starved division like HW).
Meanwhile, Tai has never shown much more than an ability to crash forward with a "knockout or bust" gameplan. If his opponent survives his onslaught of big power and heavy calf kicks, he gets picked apart. No ability to defend himself against any halfway decent grappler, either. I won't lie that it's led to some thrilling moments -- most brawlers tend to do that -- but I mean the writing is on the wall with him. The dude's durability looks to be dwindling and he's mentally checked out.
I'm fine with keeping Tai around for another barn-burner, I just don't see the sense in willfully doing so while cutting the guy who
just beat him soundly and is also a serviceable gatekeeper and has scored multiple finishes inside the UFC with a proven willingness to try and get better despite the fact that he'll never be elite.
