The name of the bunch is Moritz Böhringer, who has been allocated to the Bengals. He was a sixth-round pick of the Vikings in 2016, after a standout career with the Schwäbisch Hall Unicorns of the German Football League. He spent the 2016 season on their practice squad.

I guess I'm confused... (I know that doesn't surprise some of you), but I thought you had to be an NCAA athlete to be drafted. So the Vikings are drafting out of the German Football League?
