I think it's funny the OP keeps talking about a dynasty. The only one we have right now is the Spurs, and they aren't winning every year, but always in the mix with out any transcendent players.
Also people forget Love is 25. If he stays healthy he can play for ten more years at a high level, Rondo may last an other 6 to 8. If we got to keep Smart and/or Young, thats an other 15 years, and that doesn't included who we could get with FA's having Love and Rondo, or any picks we don't use up. We keep the Nets 2016 when the pick should be at it's best, thats an other 20 year old, and he's only 30 in 12 years from now.
I think DA's plan is getting Love for a couple of our, or an other teams pieces, send a couple of our younger guys out, but have a mixture of guys from 20 to 30 to make title runs.
