Wasn't aware Suloev, Babalu, Vitor, and Overeem were wrestlers. Can't fault Chuck for the UFC's top LHWs all being wrestlers at the time. One of whom had beat Wand.
Also the only good striker Wand ever beat was Rampage (who's striking wasn't even top notch till he joined Ibarra) so I wouldn't really tread in that direction.
These are some opponents after the first Saku fight where talks of him being the #1 LHW emerged.
Oyama
Otsuka
Tamura
Iwasaki
Kanehara
Cro Cop in special rules fight
Saku (2nd time)
Yoshida
Minowaman
Kondo
Rampage
Hunt
Yoshida again
Nakamura
Arona 2x (lost both imo)
Fujita
How are you going to say he wasn't protected?
Considering chuck barely edged out a shellshocked wand your argument holds absolutely no water. Had the same fight taken place under pride rules there were at least 3 spots where chuck would have been eating feet. CC and Hunt were world class strikers an entire division above wand, and wand arguably won both those fights. The first quality striker chuck fought put his ass in the ER. Pack it up.
