I think Saints need to get smarter so the young players can see the various options to get to the first time. As you say, Saints cannot compete on wages so need to make smarter decisions on how young players progress.
I assume the SR family of clubs are part of possible options for first team experience although currently need to be in a higher division, so that is work in progress that will currently impact those trying to get into the first team. Perhaps having agreements with other clubs can help in the meantime?
Of course not all youngsters are going to make it or agree to the plan so will be lost, but it’s trying to maximise the chances of success or getting the best compensation deal.
