I don't think you need Melo if you're getting Love. Be ridiculously expensive to keep all those guys together anyhow.
I think a Rondo/Afflalo/Green/Love/Asik team is more sustainable, plus you'd be able to afford a better bench.
I don't think Love is actually realistic. Definitely not now. Maybe next season. But this season, I think it's at least somewhat plausible you could get Melo. Since the premise of this thread is to "win now"... I created a 4 team trade that leaves us with PG - Rondo, SG - Afflalo, SF - Melo, PF - Sully, C - Asik ... Judging by the fact that nobody has come out and said, "That's not enough assets to land ___"... I'm guessing it's at least somewhat reasonable.
I expected at least one person to say, "There's no way the Knicks would trade Melo to Boston", but I guess all the value I'm giving up in the hypothetical trade and the fact that the knicks are atrocious makes it mildly rational.
