England players very rarely play for their counties anyway (even those not contracted), so it doesn't make difference who they play for. Even if there was transfer system as in football, who in div 1 is going to buy an England player who has dropped down to div 2/or already playing there if they are only going to get a couple of games a season out of that player, at best. TBH county cricket is irrelevant for KP, it doesn't matter whether he smashes div 1 or div 2, it's just ticking a box.
