The Seattle Seahawks just locked in S Earl Thomas to the highest contract for a safety and could soon be locking up Richard Sherman to the highest contract for a corner in the league, per Jason LaCanfora. The Seahawks are taking advantage of the window they have with Russell Wilson playing under his rookie contract and paying the other players on the roster to keep them around. Once Wilson has to start taking up a big chunk in that salary cap, then the team could start losing some of these players.
Thomas will be in the secondary for the next 4 years and the team is looking to lock up Sherman to be joining him for that time. Sherman has been the top corner in the game and should be getting paid like it soon.
Sherman has been in the league for 3 seasons and is just 26 years old. He has a long future ahead and the Seahawks will be looking to keep that future in Seattle. Keeping both Thomas and Sherman in that secondary will keep that defense elite for a long time.
