In part there is a degree of loyalty to the squad that got you promoted and provided 2 years of winning, if not particular an exciting brand of football.
The misnomer was that this was a "Championship squad". It wasn't it was just way better than the average League 1 squad.
The errors did not get punished, the piss poor crosses, shots miles wide, the one on ones flunked get forgotten because the sheer volume of chances created and goals scored.
The difference in this league is plain to see. I get the players are escaping criticism, but frankly in reality they are playing to their capabilities.
