Following this game, I'm firmly in the camp of moving Roberts to left centre, Kahu to right centre and finding someone to play right wing (I would have thought Maranta before this game). Reed has all the pace of a prop with a busted ankle. There are plenty of times I can recall throughout this season of Milf finding a bit of room for Reed, and Reed getting gunned down within 10-20 metres. Roberts running off that is infinitely more dangerous.
I think it would create true triple threat on that edge. At the moment, you can man up on Milford knowing that Reed won't burn you that badly. Having Roberts there = more space for Milf. I'd also point out that most of the time Reed has 'failed' to set up Oates, I think it's more been a case of Reed not being enough of a threat himself, so the defense can hold off and mark Oates (who is dangerous) until someone arrives to take Jack down. Again, if you have Roberts there, holding back for Oates is literally playing with fire.
Throw in Boyd popping up on that edge and that becomes really hard to defend against. Set those guys up properly, with a bit of depth (which has been sadly lacking this year for reasons I can't comprehend) and some good running from guys like Glenn, and that's dangerous.
