What Janis offers as a WR is only a small consideration. The Packers value special teams play and Janis is one of the best they have to offer. He will most likely make the team on his special teams ability alone just like Jared Bush did for so many seasons. The fact that he can step in as an emergency WR is an added benefit, but he is not being relied upon as a WR by the coaching staff, imo. For whatever reason, he just can't put it together at WR. The only way he will lose his spot is if another WR comes in that can provide equal special teams and receiving ability. That's possible, but seems unlikely.
