Thoughts on my team?

[Pawford]

I am winning this week 7-5-0 against the 9th best team. If the score stays the same, I will stick in the 4th position with 4 weeks left to go before the playoffs. Next week I will face-off against the #1 team.
Are any of the following players on the Free Agency worth a pickup? Who would I need to drop?
