Unfortunately, I just don't see it now from any Championship club. Ideally you want some of the teams to come up to stay up so they can achieve more, get more competitive and make the game more healthy - but the last 2 seasons we've seen a sharp decline in promoted teams as well as the gap from existing Prem teams getting larger. Forest, for me clearly bought 25 players with some experience so unless any team is willing to do that, I see all 3 going back down.
Btw, its not a Burnley/Leeds thing this. Even Blackburn wouldn't be anywhere near the standard. I watched Burnley vs Sheff Utd and whilst they looked robust, you could see none of their players have Premiership quality. It just feels like you have to get promoted with one team, sack them, and then bring in some elite experienced players that have Prem experience.
You could argue rather than have a Super League, insert a League 1.5 between Prem and Championship and we'd see better football throughout as thats whats happened now.
