Rinne-less Predators, best fourth line among week's roundtable topics

How Predators will fare without Pekka Rinne, PED use in hockey, NHL's best fourth line, last pick at the 2015 All-Star Game in SI.com's weekly hockey roundtable.

Every Wednesday, a trio of SI.com staffers will sit down for a discussion of the hockey world's hot-button issues. This week, Sarah Kwak Brian Cazeneuve and Al Muir talk about injury trouble in Nashville, performance-enhancing drugs in the NHL, the league's best fourth line, and our picks to shine at this weekend's All-Star festivities. First up:
