English league 1 & 2 teams will once again be in a position to offer better wages than the likes of Hibs, Aberdeen and Hearts.
Hopefully it won't make a great deal of difference to us but if say Hibs and Sunderland were both looking at the same player they'd be able to blow us out the water with the wages on offer.
