What players clearly recognise (something which many of our fans clearly don't), is the difference between what players like KDB can do and other just 'excellent' players.
He might not have been at his mercurial best for the whole season (especially when he was out injured for that little period :)) but he is a risk taker, a difference maker, call it what you want.....but the players aren't stupid (believe it or not)....they see what he can do as standard just isn't normal for 99% of players and that is why he gets recognised for it and voted for. Plus he is clearly humble with it, too....which helps, as other players won't vote for pr1cks I imagine.
So whilst Dias was tremendous for us (something we as fans, rightly recognise), it is a lot easier to be a damn good defender than a 'game changer'.
Anyway, that's my opinion for what it's worth (be grateful at this point if no-one questions why Henderson won it over Kev two years back - I genuinely have no answer to that!!) :)
