The Seahawks defense has been outstanding this season, ranking first in fewest points allowed and fourth in fewest yards allowed. But the most impressive thing about the unit could be that Earl Thomas is the only starter drafted in the first round. He was chosen 14th overall in 2010.
By way of comparison, the teams ranked directly above the Seahawks in total defense have at least three first-rounders among their starters. Pittsburgh and San Francisco have four each, and Denver has three.
