I don't think he can be really judged off one international game this weekend. BA will know him well enough to know his weaknesses in defence, and hopefully but a structure in place to not get him isolated. Looking at his highlights/tries, he seems to score the same try over and over again, which implies teams can review it and try to defend against it, but he'll still score. Really confident in the backline to get some good metres out of backfield and set a platform for the forwards. Hopefully it enables Ackers to run at broken lines a bit more.
PS: the video of Maika's dad coming over to surprise him for Fathers Day is brilliant.
