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...
Goals
4 tied with a pathetic 1: Liles, Clark, Sauer, Finger
Assists
Liles (5)
Points
Liles (6)
+/-
Sauer (+7) (Scott Hannan is a team-worst -8)

Sauer and Leopold both with 6
Total Ice Time
Hannan (23.5 Minutes per game)
Shifts
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).
Giveaways
Liles and Clark each with 10
Takaways
Hannan (6)
Blocked Shots
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.

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
PPGFOI
(number of times a player is on the ice when a PP goal is scored by the team)
Liles (8)
SHG, Pts
Finger is the only D with SH Points, 1g, 1 pt
PPGAOI
(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)
Min/PPGAOI
Highest TOI/PPGAOI (this is good - it's how long a guy is on the ice on the PK between goals allowed)
Skrastins (15.6)
