Who to bench this week?

[bobby_vee]

First time in a while I have most of my players in and con't decide who to bench:

MID: Ablett, Watson, Boyd, Selwood, Pendlebury, Priddis (Treloar, Crozier)
RUCK: Cox, Sandilands (Big O, Randam R/F)
FWD: Dangerfiled, Sidebottom, O'Keefe, Roughead, Matin, Zorko, Fyfe (Tippett, Random R/F)

Players in bold are Mid/Fwd DPP.

I am thinking of moving Roughead as an emergency for the ruck, and bench Martin in the forward line and have Tippett and Treloar in the forward line. Roughead has been great all year for me, and only has had 2 games under 100 since the bye. Martin has been too inconsistent to bank on him scoring a 100, and Treloar and Tippett should score more than him, although I do have little confidence in Tippett at the moment as well.

Or do I leave it as it is, and just swap Martin and Treloar around...or do I keep Martin on the field?

Thanks in advance.
