Yesterday they signed Callum McFadzean from Crewe - another L1 regular dropping down 2 divisions to join them.

They're definitely signing players at their peak (ie late 20s and 30s) with history of promotion, presumably on expensive contracts. This might do the trick for them. But if it doesn't get them promotion this season it could go terribly wrong.
Whatever you say, Stockport and Wrexham are both looking favourites for that top spot now. We're going to have to play out of our skin to stay up there with them.
