I think I agree with this simply because there are nooooooo guarantees in the nba for rebuilding. It's not like the NFL where they give you a top draft pick for losing, you get a great QB, a favorable schedule, trade down for more picks, and suddenly in two years you're back like the Lions or something.
I agree. I am always wary of people saying we need to tank to get a high pick. The system for getting high lottery picks is only very vaguely correlated with having a bad record; it is very easy to have a horrible record and STILL not get the good picks (see: Boston 2007 draft ... that still irritates the hell out of me, we have the second worst record in the league, but still miss out on Durant and Al Horford). Furthermore, even if you DO get the number one overall pick, there's no guarantee you are getting a franchise player.
Look at the last 10 drafts, or so:
2001- Kwame Brown. Bust.
2002- Yao Ming. Great player but very injury prone.
2003- Lebron James. Okay, this is a good one.
2004- Dwight Howard. Another great one.
2005- Andrew Bogut. Not bad, but no game changer.
2006- Andrea Bargnani. Blergh. Not HORRIBLE, but not franchise at all. Barely an all-star.
2007- Greg Oden. Injury prone, wasted potential.
2008- Derrick Rose. MVP.
2009- Blake Griffin. Future MVP.
2010- John Wall. Not horrible, but not great.
2011- Kyrie Irving. Anyone really excited about this?
There are 4, maybe 5 players you can build a team around here, 1 complete unknown (Irving), 4 decent players, and 1 complete bust.
For half of those drafts, the best players to come out of them were lower picks.
