It's not a bad point to be fair. When you do stuff that's not by the book, not textbook, not taught in gyms, then yes it can catch people off guard and work really well. Soliman is a good example, he had that awkward herky jerky style that people can struggle with.
Another example is Mayorga, unpredictable without the typical rhythm and style of a boxer, and had more success than he should have Vs elite boxers.
Maidana too, but Maidana had a lot of attributes that put him well above the other two.
Nevertheless calling it "great footwork" is a bit retarded. Great footwork is knowing where and when to move, reading your opponent, being able to manoevre them into position, get out of position efficiently, with the least amount of movement.
Cruz's random footwork is just that, random nonsense. And the sort of thing any fighter could do if they chose to.
I feel like Cruz is somewhat lucky to have fought in MMA and the era that he reigned in, in a developing division. Against more skilled fighters with better boxing, he would have been caught a lot more often. A bit like this.
