I'm a Arlovski fan, and the first UFC DVD I bought was UFC 51 because it had two muscle guys on the cover that looked like they're probably good: Vitor Belfort, Andrei Arlovski. I think during Arlovski's UFC championship reign, the better HW's were in PRIDE and Arlovski's UFC opponents may not have been top HW's. Modern day Werdum is better than UFC 70 Werdum.
I still would like to see Arlovski vs. Frank Mir, Crocop, Josh Barnett, Big Nog. For some reason, I look forward to watching Arlovski but not JDS/Cain/Carwin/Lesnar.
