On the question of Hastie, I have yet to hear a compelling case as to why he was signed in the first place. The whole situation suggests confusion and bumbling on Rangers part.
In future, when contemplating the signing of a young prospect, the following questions should be asked:
Do his skill-sets, his strengths, represent a need in the squad,
What exactly must to be done in terms of coaching to develop those strengths to a level where he would be regarded as a potential starter on the first team squad.
If the intention is to sign and then loan the player out, which team would represent the best environment for his development to take place (this would of course require regular monitoring of the players progress to ensure that everything is on track.)
Lastly, the fees and finances involved - is the potential risk/reward likely to be worth it?.
Of course there always is subjectivity in decisions as to who and who not to sign. But a template such as the above (or something like it), should be used as a matter of course by the scouting staff in consultation with the manager and his coaches, before making decisions are taken as to which young players Rangers might consider signing. Doing so, might at least help bring some rationality to the process.
