Every year there is that surprise player who gets cut right before the final 53-man roster. Most fans debate his presence on the roster all year. Those for keeping him on the roster claim he has no chance of finding his way onto the practice squad. The other 31 teams see what this particular person sees, and they will scoop him up. However, in most cases, this rarely happens.
The first important note to remember is that teams cannot claim a player to put on their practice squad. To claim a released player off of waivers he needs to make the active roster for three straight weeks.
