i honestly think it is down to the sheer weight of expectation that these players suddenly realise when they walk into Villa. Elphick is a classic case in point. At Bournemouth he would have been a big fish in a very small pond. Suddenly he's skipper of a club of this size and all the hope more than expectation that goes with it. This must have something to do with it. You don't become a bad player overnight. I watched elphick a few times for Bournemouth and you could see why RDM bought him.
