This era was so competitive and each fighter had great runs.
Wands run from 2000-2007 is 1 of the most brutal reigns of terror and my favourite.
But honestly I can't separate
Wand
Rampage
Chuck and
Shogun. All had amazing runs but all lost fights.
I Also highly rate Randy's run at LHW. The way he blew threw Tito, Chuck and Vitor was amazing and I truly believe that versions of Randy has a great chance at beating all of the above.
Hendo is another fighter I find hard to rank, because like Tandy he jumped between divisions
