Without Lillard this past year in the draft, the Blazer would have been shitty and maybe won 20 games. This team would be horrible right now if Lillard had been a bust, which happens all the time at #6. I find it difficult to get upset because the best possible pick was made at #6.
OKC missed the playoffs in both of Durant's first two seasons and won 20 and 23 games in doing so. They were still really bad until his 3rd season.
You forgot about Dwyane Wade (#5 pick, two titles, both for the team that drafted him, one as the best player). But aside from that, it's a valid point. Of course I'm in the apparent minority that doesn't believe that our team needs to be a title team in order to be successful. I LOVED our early 90's teams, even though they never won a title, and still consider them to have been very successful. Maybe I romanticize them because I was in middle school at the time. But if we could build a team that could win a few playoff series', make the WCF a couple times, and give us something to believe in, I'd be satisfied--title or not.
