I think it's too early to tell if that is true. A full reckoning will come once the retained list is released and it becomes clear what liabilities he has left the club with versus promising players brought in. I'd be surprised if they challenge next season.
I’ll be very surprised too as under Evens they punched above their weight. They were heading out the league when he came in and he got them promoted in his first full season.
He can’t have left Rotherham in that bad a position either if they are keen to have him back. Odious he might be on a personal level but he is undeniable a top manager at this level.
