When Nash wanted to go, he could go. Don't let the last few years of WCW fool you. I would argue he was the best big man in the US between 1994 (after the decline of Vader) and early-mid 1997. Maybe even longer than that, because Vader was just not good after 1994, and Taker wasn't shit in the ring until 1998 if you're generous, 2001-2002 if you know what's up. He gave up after a while in WCW because he didn't have to try to get paid, but once in a while he'd still have some flashes. I enjoy both matches with Goldberg (Starrcade 1998, Spring Stampede 1999), and he had a couple of really good matches with Booker towards the end. It was in WCW's HIAC and was full on "I'm putting this dude over as hard as possible" mode for Nash. He and DDP had a pretty good tag match against the NBT somewhere around that time as well.
