I agree with this [Free agents Saints should consider]

Apple is a no-brainer. Now, as for the others. I'd love to get Peters. I don't think he is a long-term guy any longer, but as a backup for when (not if) Armstead gets's hurt he would be a great insurance policy. Clay Matthews would be a very good backup, or starter on 1st and 2nd down. Gabriel would be a long-shot, but at least he would provide competition. And, if he could get back to what he was for 1 season, then that would be lagniape. Good list of players.
