Backline issues, please help

[Capper]

I have been looking after this team since about R4 for a friend overseas on holidays and i would like to know your thoughts on improving it.

She started with a line up of
Def - Peter Faulks, Tom Bell, Rhys O'Keefe, Jordan Kelly, Jarrad Boumann, Marty Clarke, Brodie Martin, Tom Gillies and Karmichael Hunt.
Mids - Ablett , Mitchell, Selwood, Jetta, Judd, Masten, Pearce, Ross   
Rucks - Naitanui, Goldstein, Redden, Jenkins
Fwds - Franklin, J.Kennedy, Cloke, Pavlich, Petrie, S.Johnson, Koschitzke, Byrnes, Roberts

I have completed several trades to get some money in and try and fix this backline but with the likes of Paine and Spurr not playing that has also hurt.

Current team line up is:
Def - Deledio, Hunt, Spurr, Clarke, Mohr, Grima, Darley, B.Martin, Sam Shaw
Mid - Selwood, Masten, Jetta, GAJ, Mitchell, Judd, Neale, Gibson
Ruck - Naitanui, Goldstein, Redden, Jenkins
FWD - Pavlich, Petrie, Johnson, Cloke, Brown, Zorko, Franklin, Koschitzke, Crozier

7 trades left, $259,100 in the bank. Thoughts??

i was thinking of Mohr/Martin to Scotland
