Why don't you try looking up his record? Mike Brown ended Faber's winning streak. Brown defended twice against Faber and Leonard Garcia before losing to Aldo. Considering that you don't seem to be familiar with recent history as far as the lineage of the titles are concerned, I'm not going to bother continuing any debate about who should be ranked where on the P4P lists.
All of the fighters on your list are good choices - but some of these guys haven't established enough of a run or had significant enough wins to be worthy of inclusion. I think I'd drop Cruz, Sonnen and Dos Santos. I'd have to slide Dan Henderson in around five or so and add Melendez at nine or ten perhaps. Something like this: 1. Anderson Silva 2. GSP 3. Jon Jones 4. Cain Velazquez 5. Frankie Edgar 6. Dan Henderson 7. BJ Penn 8. Jose Aldo 9. Gilbert Melendez 10. Vitor Belfort
