This question was asked prior to the draft, and it's a question that needs to be asked again:
The St. Louis Rams cut Sam on Saturday, which stopped him from becoming the first openly gay player to make an NFL roster. The Ravens were interested in him leading up to the draft, and there were reports that the Ravens were going to make a run at him if he went undrafted.
Sam just doesn't fill a pressing need for the Ravens. He would be a 3-4 outside linebacker for the Ravens, and the team is already carrying 10 linebackers. So, the odds don't appear good for Sam to land in Baltimore.
If the Ravens or the other 31 teams don't put a waiver claim on Sam, the Rams are expected to sign him to their practice squad.
