I imagine Burgess's chances of selection depend on him getting a decent amount of game-time at the Roosters, which may be problematic. If he was still at Wigan and running them in, I'd have no problems with him and Manfredi having the spots. I've nothing against Hall, who has stood up to the Aussies before, but on his and his club's current form, he hardly demands an automatic spot, to say the least. Either of Manfredi or McGillvary would do a decent job on the right.
As for full-back, it will be interesting to see whether serious consideration is given to playing Sam T in the halves, rather than at full-back, both for club and country. For me, that's his best position. I do think Hardaker is a better defender than Tomkins, but Tomkins offers more in attack and as an organiser. Difficult choice.
I don't why Widdop merits an automatic place, as many seem to assume.
Prop is interesting, too. The Burgess twins (and their whole team) haven't been pulling up too many trees this season.
