The Seahawks are finding out for the first time how difficult life without Earl Thomas is. Since he sustained a season-ending broken leg in Week 13, they've yielded more than 30 points twice in the past three weeks after not doing so all season.

Seattle took a step Friday to try and ensure it won't have to adjust similarly to the potential absence of another key defensive cog, Michael Bennett, who signed a three-year extension, the Huffington Post's Jordan Schultz first reported. NFL Media's Ian Rapoport says the deal for Bennett, the 32-year-old two-time Pro Bowler, maxes out at $31.5 million with $17.5 million guaranteed.
