Decent idea, I've only got 9 trades left and this Kennelly thing has really stuffed my team up. Duffield would be a solid addition to your team.
Yeah I've got 9 trades left as well.
I'm thinking that I'll bench Kennelly this week and then trade him a week later. Most of the players I have on my radar look like having high break-evens this week, so I should be able to pick them up cheaper in a week's time. For instance, Duffield, H.Shaw and S.Fisher.
Another option could also be the completely bottomed-out Hargrave, who got a good score on the weekend.
