Out of that choice I'd go O'Keefe and Franklin. Unsure on O'Keefe's preseason status though, think he's been injured and will only resume full training over the next couple of weeks. I think Goodes will start to decline and his scoring will suffer. Very inconsistent last year after being thrown around and up forward. Really to be honest though, I'm not in love with either of those Sydney options.
Disagree, he can destroy by playing in the midfield and having marking superiority, I'd rate him more than you are suggesting.
