OA site is back up now.
BJ has some recent form
3rd in a sprint against some middle-ranked (100+) Europeans and 45/55, 8 mins down, in a classy middle won by Pasi Ikonen. But, he's still shown in IOF rankings as belonging to GBR, and his ranking of 309 is lower than Bruce, D Brownridge, L Hallett, Ev, JoshyB and C Naunton, and not much higher than Ecmo, Hoggster and Blair.
Not sure whether the selectors have used these or other non-WRE events as the basis, however in the absence of Robbie and Shep, and with his previous WOC experience, a useful addition for the sprint and relay - provided the nationality issue is fixed. Good job orienteering is not in the Olympics where it isn't easy to change nationality.
