Davie, Fla. ? Three years ago, the New Orleans Saints decided Ricky Williams was worth an entire draft. Now the Miami Dolphins believe he could be worth two first-round picks. The Saints traded Williams to Miami on Friday for draft picks: a first-round choice in 2002 and a third-rounder in 2003 that could escalate to a first-rounder if Williams rushes for 1,500 yards this year.
