Indeed they do. Yes there are many that build people up to be so much more than they are. There are though very few who can then live up to that hype, VVD being one of them.
You then have people with short memories or with a complete lack of awareness of "istree".
VVD may have been good in previous seasons, he may get back to that previous form, but there is also the possibility that he may never be the player he was. Down through the years there have been promising players (Brian Clough) and proven stars (Colin Bell) who have had bad injuries and have never been able to re-capture those highs/standards.
What VVD did in past seasons, Dias has taken on. Shown how a classy defender can shape your team, give them confidence and allow them to play more. Dias, in my view, head a shoulders above the rest and clear and worthy winner this year.
