I think about the logic behind that and I'm not so sure it's correct. The assumption is that if you go up too quick you'll come back down, but there's a chance you don't as well. Given the opportunity and being in that position I would like to think I would choose to give the players that have brought you to this point a crack at the big time and then look to strengthen in the January. Different on a case by case basis but in this instance I think that's what I would do, a lot of hungry players in that squad who if they can keep together and get promotion will either be able to battle at the bottom of the PL or will go back to championship at which point the money from being in the PL and then dropping out will be decent enough to build and look to get back in. I suppose it depends how far you sink and what you're coming back up with etc. I personally think Sunderland have a squad that could push into the PL and think those who have been there since L1 should be rewarded. It's like spending years on a project at work then your manager taking credit for it or worse, them offering you redundancy/replacing you and acting as if the person coming in is responsible haha! At least let the players who've played since L1 have a crack at it.
