Because he knew with the squad we had in the NL last season it was highly likely he'd get a promotion under his belt. To me it seems he used us as a stepping stone back to Swansea. He was always going to go back to swansea even if we were top of the league by 10 points. The Notts job was never a long term project for him the same way we see it.
Great to hear Stu and the team will be moving to Nottingham, shows true commitment.
