Maybe we're at opposite ends of a circle

. I remember when Shaw broke through. We were desperately looking for a left back and couldn't get one so Shaw was the only option. Had we bought someone in, who knows? But he was able to develop. As you say, these guys never will. But is it because they aren't good enough or because they aren't given the opportunity. We'll never know.
Regarding your last point,
I don't think we are significantly different to Stoke or West Ham, other than they don't get their team picked apart every year.
