2013 absolutely was NOT fun.  I sat through every regular season game hoping that the team would show signs of life and turn the ship around, but it never happened.  Getting destroyed by a mediocre Knicks team (they should have swept us honestly, and probably would have if Melo drained free throws near the end of game 4 like he usually does) was extremely frustrating.  
I was pro-tank last year because I knew how horrible we'd be.  It was year 1 of the rebuild.  We'll very likely be terrible again this year.  If we were a mediocre team with aging vets and few assets, then yeah I wouldn't be thrilled with sneaking into the playoffs only to get swept in the first round.  But for a young, growing team like ours, I'd like to see us improve gradually until we finally make a big trade to get us back into contention.  That said, I think it would be great if we made the playoffs this year.  Not rooting for a tank again unless we're absolutely terrible by mid-season and losing is clearly the best thing to do again.  And I'm confident we'll never get a top 5 pick... ever.
