I think they will pick 22-23 (and rightly so) as Hudson just gets so little time with his AWs players - and who knows come the qualifiers later in the year who will be & who won't be available.
There are some who will be picked, whom he won't have coached for nearly 12 months (Oman game), or more.
A squad of 22 also gives him the option of nearly fully opposed training sessions.
