I agree with manon on this one, I am in a similar position with 2 of my trainees, iI have contacted the NT scouts and was told get OD & JS to 13 then we will go from there.
Whilst this might fit great for this particular U21 NT, it wasn't really in line with what I believe will make the 2-3 headed monster combo guard arrangement for my teams future. So I will try and meet the needs of the NT, I will still go ahead with my program for my team and if a bonus comes along of a call up or 2,then happy days!
