Backline Upgrade Advice

[DirtySeppo]

Here is my team:

D: Hodge, Carrazzo, Enright, Malceski, Waters, Fisher, Webberley (Maguire, Silvagni)
M: Bartel, Barlow, Goddard, Cooney, Cassisi, Montagna, (Gysberts , JKT)
R: Sandy, Cox (Lobbe, Warnock)
F: Pav, Gia, Buddy, Hall, Brennan, Grundy, Pods (Fyfe, Watts)

I have 6 trades left and I have three straight matches against other teams in the top 8.   I want to upgrade Maguire with Webberley & Silvagni not providing much coverage.   Barring any LTI, I want to not trade for 4 weeks ideally.

I have $120k so here is who I have narrowed it to:

1. Gilbert
2. Kelly
3. Waite

The reason I put Waite in there is it gives me a DPP to move swap out Grundy to BL and VV.   

All feedback is much appreciated.

I would say Gilbert, though he is the most expensive

Corey coming back may affect Kelly's scores
Waite does give you the option of a MPP but is more likely to get suspended

Why not get Grimes he is at the cheap price of $314,800
or
Duffman at $368,400
