To be fair to Surrey, they have had a concerted youth policy for a number of seasons now and a lot of their squad is homegrown. As I mentioned above, it's now that those players who are interesting the selectors and justify Surrey looking for players of a certain quality to keep themselves in Div 1 and look to win it.
Marketing wise, Surrey are also the slickest county. Their embrace of T20, making it a roaring success it not to be sniffed at. They are getting people through the gates both in terms of club and country.
It's easy to bag Surrey, but they are profitable, grow their own, and look to support Team England. Compare them to Yorkshire, who whinge in public about having England players, when in reality their central contracts help keep the club solvent, and up until this season seem to be whote ball averse, and can't sell out their Test matches in a catchment area that holds the largest number of participating cricketers in the country.
Also, in defence of Dernbach, in county cricket, especially one day stuff, he is a bloody good bowler.
