The place is way too big now, and as others have said it's not the only game in town.  It's hard to have a huge building for such a niche purpose.  I've never really heard of anyone going to Nevada Smiths for any reason other than watching soccer.  They show a lot of games but it's hard to sustain a massive, multi-floor bar based on soccer alone.  Especially when there are other options all over the place.
Nevada Smiths was the first "soccer bar" I frequented in NYC just because it was the place and the novelty of it was fun for a while.  But eventually I just wanted bars that were either less crowded, closer to my apartment or more narrowly focused (team-specific bars). 
I went back last year after the renovation and I really couldn't believe how big it was.  Not sure how they thought it was a good idea with more options popping up all the time.
