NFL free agency [VIDEO] is starting to heat up. We saw last week the Cleveland Browns wheeling and dealing and the Seattle Seahawks basically getting rid of their entire defense. This week is the week of the quarterback. Everyone knew the quarterback dominoes would fall and fall fast when they did. These quarterback moves will have an effect on the NFL Draft.

Case Keenum to the Broncos

According to ESPN, the Denver Broncos have signed ex-Viking Case Keenum [VIDEO]. The Broncos have been searching for a quarterback ever since Peyton Manning left. They have whiffed mightily on their past replacements. Broncos GM John Elway has been strongly criticized for his poor judgment in the quarterback department.

The Broncos went through a combination of Brock Osweiler, Trevor Sieman, and Paxton Lynch to cure their quarterback woes, though all have been duds. Keenum is coming off his best season as a professional. He led the Minnesota Vikings to the NFC Championship game and was efficient all season, ranking second in QBR, per ESPN.

Kirk Cousins to the Vikings

The next quarterback domino to fall was Kirk Cousins. According to ESPN, Cousins and the Minnesota Vikings have come to an agreement. The deal is reported to be, 3 years, $84 mil, per ESPN. Cousins will be the replacement for outgoing quarterback Case Keenum. The Vikings are set up to continue their winning ways that were on display last season. They have one of the best defensive units in the entire NFL. On the offensive side of the ball, Cousins will have explosive weapons to spread the ball around to.

Wide receivers Adam Theilen and Stefon Diggs will be the best receiving duo Cousins has ever played with. Not to mention, stud running back Dalvin Cook will be back from injury.

Sam Bradford to the Cardinals

The quarterback with the nickname "Sammy Sleeves" will be heading to the Arizona desert. According to ESPN, Sam Bradford has signed with the Arizona Cardinals. Bradford has been quite the journeyman quarterback throughout his career, and this will be his 4th NFL team. Per the ESPN report, Bradford's deal is only a 1-year deal. So, basically, Bradford is in a prove-it situation with the Cardinals next season. Let's not forget Carson Palmer went down to Arizona and resurrected his career, maybe Bradford can do the same. I still anticipate the Cardinals targeting a quarterback in the upcoming NFL Draft.

Can these quarterbacks take their new respective teams to the promised land?
