It sounds like silly season news to me, have only ever heard of a mass raid similar to this when Kingstonian took about 13 players from AFC Merstham a couple of years back (about tier 7) and that was simply because the Merstham manager jumped to Kingstonian who had a comparatively huge ability to pay wages.

Besides which, why would a team aspiring for European competition want to grab a hatful of bottom half of championship players?
