Schefter reports the deal will be for three years at $84 million fully guaranteed.
While fully guaranteed contracts are highly unusual in the NFL, Baldwin's tweet suggests he believes more teams will be pressured into issuing them moving forward if they want to land the top free agents.
One line coming out of Denver has the Broncos on the verge of addressing their quarterback needs.
A day before the official onset of free agency, the quarterbacks dominoes are falling into place.
The Broncos had inside knowledge into Keenum due to senior personnel adviser and former coach Gary Kubiak's relationship with the free-agent quarterback. The 30-year-old finished with 3,547 yards, 22 touchdowns and seven interceptions.
Even at 34 years of age, Williams has proven that he still has plenty of football left to be played.
Unlike other major sports leagues like the MLB, NHL and National Basketball Association, fully guaranteed contracts are a rarity in the NFL.
The Vikings have been considered the favorite to sign Cousins, who would represent an upgrade from the trio of quarterbacks - Case Keenum, Sam Bradford, Teddy Bridgewater - that were on their roster during the 2017 season.
There is likely to be plenty of rust in Bridgewater's game should he be given the keys to the Jets offense in 2018, meaning NY could bring back McCown to back him up. He was hit with the franchise tag the past two seasons, but the team has opted to move on from him this year. Sources told ESPN that he plans to sign the pact on Thursday.
The only other quarterback now signed by the Vikings is former undrafted free agent Kyle Sloter. But the Redskins missed the playoffs by losing their regular-season finale at home to the New York Giants. Brock Osweiler, who also started last season, is a free agent, and will not be back. Minnesota threw 527 times in 2017, just 13 fewer times than the Skins did.
Siemian again handily beat out Lynch last summer, but the Broncos would cycle through their trio of homegrown QBs during a 5-11 season that almost cost rookie head coach Vance Joseph his job.
