DEC 31st UPDATE: First update post-holiday break/shutdown, last of 2021. Enjoy.
Our fantasy hockey defenseman rankings project value for the next 1 to 2 seasons, and consider each player's track record, upside, age, team and injury history. Because fantasy league categories vary widely, these rankings focus on point production.
