New York Giants
This one could seem very unlikely with Eli Manning still on the roster. But the one reason that could get Case Keenum in with the New York Giants is because of the current Giants head coach.
Pat Shurmur and Case Keenum worked well together in Minnesota during the 2017 season. The success led them just one game short of a Super Bowl appearance. The Giants could look at quarterback in this year’s draft. Dwayne Haskins has expressed interest in playing for the Giants.
If Haskins does slide down to the Giants, that could be the likely draft spot for him. A quarterback room with Manning, Keenum, Haskins, and Kyle Lauletta would be quite the crowd.
Therefore, the only logical way I can see this happening is if Eli Manning is not with the Giants in 2019. It will be interesting to see. We are just exploring possibilities. The coordinator turned coach and quarterback connection is there.
