Its hard to put him in any box because he's so unique.
A fair criticism of Tony is that his DEFENSE is lacking. I don't think its that he's lacking the actual skill or physical attributes to have good defense, he just doesn't prioritize it.
Everyone very familiar with the sport will come to the conclusion that Tony has elite striking skills if you watch 10 of his fights in a row. No doubt he's willing to enter 50/50 exchanges and take big risks, but that is part of his overall package.
Considering he's on a historic run, arguably the greatest strength of schedule in the history of the lightweight division. Even if you put Khabib's run ahead of him, that would mean Tony is the clear #2 best run in UFC lightweight history.
