I know recently management have stated that they'd be completely okay with winding it back and going through another *ahem* down season and letting the kids grow. This is not a real option, because it immediately forecloses that we lose Rondo. Even if we trade Rondo for a market level deal (which is far lower than what he's actually worth), 100 cents is not worth a dollar in the NBA. You need stars to win, and unless you think we're going to hit the jackpot and draft the next Larry Bird at #6, we'd be losing our only star and it would drastically set us back.
The best case scenario if we lose Rondo is that we follow the Pacers method, get lucky in the lotto and spend the next SEVEN YEARS REBUILDING. And in that best case scenario, the Pacers are still not good enough to beat the Heat or Spurs, I'm not convinced they are even good enough to beat the Thunder, Grizzlies or Warriors if they were in the West.
Theoretically, those Brooklyn picks could turn into Kareem, Lebron, Bird, MJ, and Magic, but realistically we're looking at a painfully long rebuild where it is a longshot at best to actually win the championship. If we lose Rondo, to get a player of his calibre back we're going to have to overpay, because again, 100 cents doesn't make a dollar in the NBA. Even 125 cents doesn't make a dollar in todays foul driven NBA.
Sitting idle and hoping we win the lottery is a terrible, lazy, strategy. The Cavaliers have WON two of the past three and were still the 9th worst team in the NBA this past season. This is the highest our assets will be worth and our last chance to keep Rondo here. The alternative is spending the next 7 years praying for the lottery or trading 150 cents on the dollar for getting a comparable player to Rondo back.
