Here's the unofficial list of the leaders (defensemen only) in a big variety of categories. All stats are through 13 games and compiled by me...
4 tied with a pathetic 1: Liles, Clark, Sauer, Finger
Sauer (+7) (Scott Hannan is a team-worst -8)
Sauer and Leopold both with 6
Total Ice Time
Hannan (23.5 Minutes per game)
Hannan (30.3 per game)
Liles (26 or 2.0 per game)
Finger (15, 1.7 per game) note that's 1.7 per game he has played (9), not the team (13).
Liles and Clark each with 10
Clark (33, 2.5 per game)
Interstingly, Liles already has 22 blocks. He's on pace to more than double his 68 from last year.
Hannan (17.8 per game)
Clark and Sauer each with 1
Liles (5.0 per game, almost double the 2nd D - Clark)
PP G, A, Pts
Liles is the only D with PP Points - 1g, 4a, 5 pts
(number of times a player is on the ice when a PP goal is scored by the team)
Finger is the only D with SH Points, 1g, 1 pt
(number of times a player is on the ice when a PP goal is scored against the team)
Clark and Hannan each have 6 (ok, this one's not a "good" stat to lead, but it's here for the sake of completeness)
Highest TOI/PPGAOI (this is good - it's how long a guy is on the ice on the PK between goals allowed)
