I think we should stop considering moving a 10 or 12 to fullback. We will need options in these most important playmaking positions, so I'm sure we can deal with what we have already at the back. Gits, Barnes, Cooper and Mortlock will probably all spend time in and around 10/12 this season (with all but one of those players able to play both positions), and Beale may well get a shot as well. The other big question is whether AAC (Adam Ashley-Cooper) will get ahead of Mortlock in the 13 jumper at some stage. I must say though, I don't mind the prospect of Cooper lining up inside Morty in 12 and AAC (Adam Ashley-Cooper) in 13 in the odd game. Short or inside balls to a straight running Mortlock or long passes to AAC (Adam Ashley-Cooper) on the outside of his man. Gits on the bench.
It would be wrong on so many fronts to consider Cooper at 15. He is the most skilled attacking 10 we have. Long passes, short passes, inside passes, step, speed off the mark and long and short kicking game. Beale misses out on long passing and long kicking to an extent, Gits missing out on long passing as well as directness of play. Obviously Cooper is still a work in progress, but in my opinion he has the ability to take the 10 position so far past what Giteau can offer it isn't funny. He may even be able to take it past Bernie.
As far as the topic, I'd opt for Shep, although it is a concern that he keeps being played on the wing. As far as the pace issue is concerned, I don't think he is as slow as we think, and definately not that much slower than Latham. Mitchell is a clear second, and I think McLinden is worth keeping an eye on.
