The problem with the rule changes is that anyone who played a lot, performed well, and got injured can make the PS. However, once they're healthy, if you want to keep them you better activate them or risk seeing another team grab them. Which raises the question of how you effectively hide they're being healthy from a team who senses someone should be okay by now based on the nature of their injury, as in Goodwin's ribs. IR can become a safer option in this regard.
