I think the designation was done to allow a player to get a chance to latch on before the last min. They can sign elsewhere while the team still gets to save money.
It will go away when they put up effort and stop it. Get a giant nose that eats at least 2 blockers and can drive a lineman back. Goose and Adams with the rest of that d could have stopped that play. When teams bring it all inside to sell out on a stop they will start passing out of it.
