Good luck to Stuart - he always seemed like a nice guy, and had our clubs interest at heart. Heck of a job he's got on his hands now, mind.
However, if you look at the teams that have been automatically promoted in our two years in League One - Bolton, Sheffield United, Wigan & Blackburn - they have all been stocked with Championship players on Championship wages. And none of them have had even close to the resources that Sunderland will have next year with their 2nd season parachute payments (which under the new PL TV deal are colossal) and 30,000 crowds.
Yes, Sunderland are wasting a ton of money on bad players that they seemingly can't get rid of. But assuming at least some of those contracts are expiring, their buying power will dwarf anyone who's ever played in the third tier of English football.
If they hire a competent manager (be it MApp, or someone else) then I would have them 10/1 on for automatic promotion.
Bolton, Birmingham & Reading would also have a big financial advantage over us as well. Burton wouldn't though.....they'll fit back into the middle of the pack financially.
