The vast majority of youngsters that have left in this transfer window are not good enough four our first team (and I do mean our current first team). MacKay looked decent when he first got into the team in D3 but didn't kick on after that and Aird is a much better option out wide than him. Robbie Crawford just isn't good enough (he wouldn't get in the Hibs, Hearts teams for example) Gallagher might have something but there's no way he's getting in a head of Boyd, Miller, Daly or Clark so best to get him half a season of first team action under his belt. The rest? I highly doubt we'll see any of them in a Rangers jersey again as they just don't seem up to scratch.
