That's really the thing isn't it? Im sure i wasn't the only one who thought about Romero vs Weidman as well. Difference between that and this is that that came in the third round, after Romero had spent the previous two rounds gathering information, picking up on Weidman's predictable attack habit.
Whereas in this case, Masvidal predicted he would change levels right from the opening bell. And honestly, why not, just in case it works?
Before this fight a lot of people were drawing comparisons with the Maia fight. One thing you can say about Maia, he almost always manages to find a way to get in close; even in the fights he loses he'll still often get in multiple times a round without taking much punishment (it's actually doing anything once he's in close that tends to be his problem, due to a one note single leg attack and lack of clinchfighting capacity).
So both are the same in the sense that opponents of either will know that they both only really want to do one thing, yet one was predictable in a way that the other has not been; predictable in the sense of not what he is doing, but when he is doing it. Maia's measured and judicious use of feints to sus out what the opponent wants to do before making a commitment and deaden their reactions are a good wrinkle to take away.
