I think we approached the question differently.
I look at it this way, any one fighter's abilities is made up of Skill, Athleticism, Intangibles (heart, desire, motivation, etc), durability. The "Skill" part is the technical know-how in the different disciplines and aspects of MMA. Jacare's skill level in BJJ is very high, his wrestling is high also, his striking is decent. I think Jacare's overall "skill score" is higher than Whitaker's. However Whitaker beats him in Athleticisim, maybe durability and at this stage the intangibles probably.
Just like with Anderson, I thin overall "skill", he's the highest. But I think he would get smashed by Whitaker, Romero, Jacare and Rockhold.
That's just the way I interpreted the question.
