Here's how I would justify it if I were the GM of the Clippers.
We have the 8th pick and the 54th pick, but only 5 players under contract. This is widely considered to be a deep draft. The dropoff between 8 and 23 is big, but not staggeringly big. If we can get a solid rotation player with the Portland picks at 23 and 34, along with a known quantity in Rudy Fernandez, who showed a lot of promise in his rookie season before falling off last year with injuries and a sand filled vagina, then we'd be getting three cheap players who should be ready to contribute. My franchise has blown it with top picks in the past, so why not try a shotgun approach by picking up three players and hoping one of them pans out?
Pretty well justified I think.
