But by final cuts, he was the only option. They surprisingly released bargain free agent Anthony Smith because of poor special teams play and concern about a chronic groin injury and assignment consistency
Apparently that is why Smith was cut. I was unaware of the 'chronic groin injury', I assume he wasn't good at being a consistent player because that is why the Steelers released him and if you are a back-up, you better be able to play special teams.
The Packers put an emphasis on special teams and I am glad that they did... In my opinion, it already helped big time in the first game.
