this may be true (it is), but Hudson was still going on like he was the No 1, so clearly had bad intel
No Hudson didn't.
If you listen to interview when AWs squad named, Hudson said Moss was competing for keeper spot at Newcastle, and taking him to Japan would hurt his chances of nailing that spot. Basically him and Moss consulted, and agreed best Moss stay in The Castle, in hope Ernie would pick him.
