I'd take #1 and run away. Steal in my opinion, depending on what kind of protection is on that pick.
Intrigued by 2, mostly because this 2014 draft could end up being the best in quite some time. Tons of potentially elite talent.
No thanks to 3.
No thanks to 4 - I like Kanter, but I don't like the other pieces well enough to ship out Rondo.
Iffy on 5. Prior to this last season, I would have put this in the same category as #1 - take it and run. But after Love's poor attitude, injury issues and poor performance when he did see the court, I'm not quite so interested in him anymore.
I'd do 6 only if Pierce was moved in a similar trade and we were making a move to stockpile young talent with upside.
