Your problem is you don't seem to understand much at all.
He wasn't sacked after 6 games, he was sacked after 8 wins in 28, you don't start fresh every time a season starts and your form from the season before continues, I know it's rare we have a manager that finishes one season and starts the next but his dreadful 6 games this season were at the end of poor form last season.
No worse off? If Nolan was still here we might still be looking for our first win this season and we literally couldn't have possibly been worse off than the 24th place in the league that he'd left us in.
