The fact is that they hadn't made the finals for 6 years and weren't prepared to risk it, draft a whole bunch of prospects and HOPE they turn out to be superstars. Even still, they would have been out of the finals still till about 2011, which would have made it 10 or whatever years since their last finals appearance.
With Judd, they are a finals team within 2 years, and get rid of the risk of drafting prospects that may turn out to be nothing.
So yes, I think Carlton did the right thing. We really don't know what Watts/Morton are going to become, and considering they already had 3 No. 1 draft picks, they thought that it was better to build around a superstar like Judd, instead of fill a team with No. 1 draft picks, where the risk is that they won't make the finals for another 4-5 years. I guess they were sick of losing, and if we're still in the same situation in 2012, having still not made the finals, I would trade for a superstar like Judd, instead of drafting and losing for another 4 years just to get some good draft picks.
