Late advice

Just need some advice. I hear that rohan wont get named this week and with rockcliff probably not going to be either, should i put in gumbleton for one of the two before the lockout.?? Also not sure now bout robbie gray as there is some bout over him. Also dont know bout bernie vince, thinking bout an upgrade to boyd. This is my team atm:

D: Goddard, Enright, Hodge, Harbrow, Waite, Kennelly, Waters (Maguire, Nason)
M: Ablett, Dal Santo, Vince, Trengove, Martin, Jetta (Barlow, Bastinac)
R: Clark, Natanui (Warnock, Trengrove)
F: Riewoldt, O’Keefe, Franklin, Gray, Tippett, Hall, Rohan (Rockcliff, Podsiadly)

Bank - 39,000

Thinking of getting rid of rohan for gumbleton, gray for harvey and vince for boyd.
Are these good ideas?
Any suggestions would be great, cheers

I replied to your P.M sobey.
