Dimitri Filipovic is joined by Jack Han to answer listener questions about implementing new systems during the season, the impact of handedness on defensemen, who drives a team's underlying defensive results, and how to fix notably lagging things like Minnesota's penalty kill, Pittsburgh's power play, and New Jersey's 5-on-5 play. If you'd like to participate the conversation and get in on future editions of the mailbag, you can do so by signing up for the Hockey PDOcast's Discord server here:https://discord.gg/a2QGRpJc84 The views and opinions expressed in this podcast are those of the hosts and guests and do not necessarily reflect the position of Rogers Media Inc. or any affiliate.
