Parker was a very good right back and I also think Heinze was quality until he got injured and it tied in pretty much with us signing Evra, think people forget how good he was due to the Liverpool links.
Lets be honest, Rafael had that one season where he massively improved, was it the Moyes one? Apart from that he was all promise but ultimately naive and rash, he really wasnt very good during his time here bar the one year.
I dont think Shaw has lived up to his Southampton promise for sure, it was a horrible injury though. I think the main thing is his fitness, he certainly isnt world class but he is definately decent and with the DeGea contract problems its probably the one position that doesnt desperately need addressing as we still have Ashley Young.....erm, Dalot can play there. I think one thing to tale into account is he has had very inconsistent players in front of him too which hasnt helped in the case of supporting when attacking or very often, the wide players helping him out defensively. He does have weaknesses in his game but for me he has certainly done enough overall this season to warrant his place next year and there arent many I can say that for
