After the cut downs, Sam will almost certainly be released by the Rams and become a free agent. If he stays in football shape, he might get a look during the season as teams suffer injuries and refill their practice squad.
Hard to know who is going to successfully go from being a good college player to the NFL level. Very, very few really succeed at it. My guess is Sam isn’t good enough, but we shall see.
If the Rams try him out as LB he'll be ruined. The only thing he can be in the NFL is as a containment guy (DT) in pass situations.
He’ll end up in the lingerie League..........
