Trade Down in this mock draft
Those 2006 trade downs didn't work out too badly either:
(#34), choice traded to Cleveland for C Jeff Faine and the Browns' second-round pick (#43)
With the 43rd pick, the Saints selected Roman Harper.
(#99) choice traded to Philadelphia for Eagles' fourth-round pick (#108) and DT Hollis Thomas)
With the 108th pick, the Saints selected Jahri Evans.
Pretty solid dividends.
