Should Sammy have given Stewart a 15 minute debut last night when we had a comfortable lead?
Personally I would have given him the opportunity to play in a first team game when it was all over just to give him the experience. He might not be up to a full debut yet, but an appearance last night could have been a taster of things to come, both for himself and the management.
Until you test younger players, you don't know if they are up to it.
