Hayne's involvements have all been reasonably good (he had a pass and a 2 or 3 metre run in game 1, then 5 or 6 in the 2nd game), but he's quite clearly never played 7s before, and hasn't currently got the body shape/fitness type necessary for the Rugby. I think Ryans decision has been made for him unless his improvement is rapid.
Far more importantly, England are playing well, Scotland are playing well, and a handful of individual Welshmen are playing well, which is good for the Great Britain squad.
Exciting 3rd round of matches upcoming, If SA sweep the pool, then everybody else is probably on 3 wins, while we'll hopefully beat Portugal, setting up a Winner take all clash between France and Kenya, as will you guys and Fiji should England beat Wales.
