Given how many teams are lacking on the defensive line, I’d say that he has a pretty good chance of being offered a spot somewhere else. He did put in a good performance in the games he played.
But he didn't do well on special teams, and that was why he didn't make the team. You have to at least be able to play special teams, if you're projected as a 2nd or 3rd stringer.
There are by now plenty of Vets who have been cut today that will get
a team before Sam. For example, Denver cut Kevin Vickerson, a really
good vet. He will get the call before Michael Sam gets the call.
