Can I make any improvements to my team?

[Pawford]

We have one last week until the playoffs start. I am currently losing to the 2nd place team 5-6-1, which will bring me down to 4th place, 1 point from 3rd. Next week I play the 9th place team, while the 3rd place team plays the 5th. I am hoping to make a move into 3rd place to make my path a little easier if I make it to the finals.
Are any of the following players worth a pickup? Who should I drop from my team?
My roster and league categories are in my signature.
Here are the Free Agents:
I. Kovalchuk LW/RW
Z. Hyman C/LW
P. Stastny C
J. Williams RW
J. DeBrusk LW/RW
J. Schultz D
T. Bertuzzi LW/RW
D. Heinen C/LW/RW
B. Nelson C/LW
M. Johansson LW
A. Shaw C/RW
W. Carrier LW/RW
J. Spezza C/RW
D. Kahun C/LW/RW
C. White C
R. Spooner C/LW/RW
C. Talbot G
J. Reimer G
B. Elliott G
J. Howard G
L. Brossoit G
L. Domingue G
A. Georgiev G

Are there no defence available other than Schultz? I don't see much.
