After it seemed he was gone to Chicago, Seattle swooped in and kept arguably the top free agent this offseason.

The Seahawks announced that defensive end Michael Bennett signed a four-year contract, keeping him with the defending Super Bowl champions.

It's a $28.5 million contract with $10 million in 2015, $16 million over two years, $21 million over three years, according to a league source. The deal includes $16 million guaranteed. Bennett preferred to remain with the Seahawks rather than accept more lucrative offers from two other teams, according to a source.

Bennett was linked to the Bears last night, though the Seahawks came in with a final pitch to keep him. Bennett tallied 8.5 sacks for the Seahawks during the 2013 regular season and is regarded as an ascending young player in his prime.
