Darko over Carmelo because Detroit already had Prince.
Oden over Durant. Portland was warned by doctors about Oden's different leg length and that he could be plagued by injuries but they took him anyway because of their need and "you can't teach size!". Oh, and another factor? Oden had a great personality!
I ran across another article trying to defend the Oden pick...get this little gem:
I don’t care what general managers say about picking the best player available instead of drafting for need; you don’t take players in consecutive years that are very similar. As we’ve seen with James and Dwyane Wade, the two can cannibalize each other’s production instead of complementing one another while also leaving a gaping hole in the front court.
