We read what you wrote, but don't agree with it as it's complete bollocks frankly. He has hardly played for a start. If you recall correctly Evans was plunged in at the deep end at the start of last season, and did very well for a few matches. Then he got an absolute mauling from Zamora and never recovered. He lost all confidence and it took him the best part of a year to get back in the first team.
Is that what you want to see from Smalling or Jones, being played week in week out at the business end of the season, when they are not ready, under massive and increasing scrutiny every time they make an error? Because that is what can happen when you throw young players in too soon. Young players need guidance from someone with experience.
Fergie himself has always been a big advocate of protecting young players, not rushing them until they are ready. He has done it with Giggs and many, many others over the years. Was he wrong all those times? It was the right approach then and still would be now imo.
