Great topic, the pound for pound rankings are crazy right now, I would put five guys in the top ten that weren't even ranked last year in the top ten.
1. GSP (#3 last year)
2. Edgar (UR)
3. Rua (UR)
4. Jones (UR)
5. Silva (#2 last year)
6. Emelianenko (#1 last year)
7. Aldo (#7 last year)
8. Lombard (UR)
9. Fitch (#10 last year)
10. Shields (UR)
BJ (#4 last year) 2-3 in his last five fights is suspended from any p4p discussions till he has a winning record.
Machida (#5 last year) got smashed if he beats Rampage he might deserve a spot in the top ten but I'm not sure.
Evans (#9 last year) not sold on him, he could win the title against Rua and all that would do is knock Rua off the list. I'm tired of Evans fighting old guys who can't wrestle.
Henderson (#8 last year), Torres (#6 last year) both guys lost and neither really had much of a case to be in the top ten anyways.
Koscheck just has look good and win a round for me to put him on the list.
Fabricio, Cain and Junior are so tight right now that the next one to show up and fight well I would put very highly on the list.
