Time for a reality check.
We'll be lucky if the guy we draft this year, even if it's in the top 3, turns out to be just as good as love. Embiid could be a complete bust and Wiggins and Parker could be more Michael Beasley than Michael Jordan. And even if they turn out great, it's going to take a few years for them to develop. How much of Rondo's prime do you want to waste?
And while Love and Rondo probably aren't enough to do more than challenge for the ECF, having Love and Rondo makes it so much easier for Boston to attract more talent. If we're giving up Sully and a top 5 pick in this draft, I can't imagine it would take more than salary filler and, AT MOST, two future 1sts. That still leaves us with multiple 1st over the next 5 years, Green, Bass, KO and the trade exemption to try and land more stars.
I mean, Rondo/Love/Melo/Asik isn't as sexy as KG/Pierce/Ray, but it would easily be a top 4 team in the East and could be better depending on what you can put around that core.
