Arizona is now estimated to have almost $22 million in available cap space, but that's before the expected signing of quarterback Sam Bradford, who will reportedly make $20 million on a one-year deal with an option for 2019.
According to ESPN's Adam Schefter, he can make up to $40 million two seasons.
He was originally the No. 1 pick of the 2010 NFL Draft by the St. Louis Rams.
But instead it is Bradford who will replace the retired Carson Palmer in Arizona. The 30-year-old Bradford was not as fortunate in the 2017 season opener, as he sustained a non-contact left knee injury during Minnesota's 29-19 victory over the New Orleans Saints.More news: Alexa now lets you make audio and video calls on Android tablets
Bradford has had a very interesting National Football League career for a top-pick quarterback that is far from a bust, but can't quite stick with one situation.
After restructuring his contract last year, Robison said he wanted to play two more years with the Vikings and likely retire after the 2018 season.
Staying on the offense, the offensive line is a unit that could use some upgrading, as the Cardinal quarterbacks were sacked a combine 52 times in 2017. Bradford completed 71.6 percent of his passes for 3,877 yards, 20 touchdowns, and just five picks. He was traded to Philadelphia in 2015.
In other roster moves, the Cardinals announced that they have released running back Adrian Peterson after a half-season in the desert that included a pair of impressive games and a season-ending injury.
It remains be seen how hard the Vikings will look to retain Johnson, who made $2.35 million last season.
