Negative ese, Nick has won a ton of huge fights, hence the reason he was the Stikeforce WW champ for the last couple years. He also tapped out Takanori Gomi in 2007 when Gomi was the #1 LW in the world on one of the last ever PRIDE shows, he tapped him with a gogoplata which had never been done in an MMA fight before.
Evan Tanner probably wouldn't be a good choice, he was never more than a gatekeeper at the end of his career. He won the UFC MW Championship before the UFC blew up and was talent rich, after he lost the belt the sport passed him by. RIP though.
Wanderlei or Fedor would make great choices. Tito Ortiz might be a good choice also since he was the first MMA fighter to cross celebrity boundaries and had a 5 year reign as the UFC LHW Champion.
