All-Stars are by nature rare, but you have a much bigger chance at getting one earlier in the draft. I understand your thoughts and there are two sides to this, but I don't see the value of getting swept in the playoffs as bigger than the 10% chance at getting in the top 3. I also don't think the mix of Rudy/Favs/Rubio will click enough to get us to the playoffs. It will be an uphill battle for sure.
We can definitely get lucky later in the draft and that is why would should sell off win now pieces for late first rounders if those deals are available. More chances = better luck. I'm not in love with the 25-40 range players in this draft though, so if that doesn't work out then fine.
Not gonna kill anyone that doesn't want to tank but there is definite validity to the strategy and the worst place to be in the NBA is 12-14... GMs feel close enough to reach (I trust DL) and short cut the process to get mediocre. Not close enough to the top tier talent to string a couple good drafts in a row but you have a couple pieces that are good enough to get you to 35 wins... its a tough cycle to break.
I wish so much that we had a redo on the Rubio trade. He's a fine guy and tries really hard, but if we had that space and pick back I would feel so much better about the future.
