I don't get why people are down on Spielman. Yes, he made the Ponder pick, but his overall record in the draft has been very, very good.

Spielman's 1st draft was 2007. If you accept the premise that teams are built in the 2nd - 5th rounds, it's hard to argue he's been "very, very good" unless you just like arguing.
