(Renton, WA)  --  After just three days on the practice field during the rookie minicamp over the weekend, Seahawks defensive coordinator Ken Norton Jr. already likes what he sees.  Six of Seattle's 11 draft picks this April were defensive players, including two linemen, two linebackers and two safeties.  The Seahawks also restocked after the draft, adding 12 undrafted free agents to the mix.
