Short memories.
Don't you remember any games from last season? Southampton. Arsenal (twice). United. Liverpool. Spurs. Atalanta. Lyon. Leicester.
All of those games significantly worse than anything we've seen this season. Some of the worst performances I've seen from an Everton team since the 90s in there.
So many of the victories last season came from worse performances than some of the draws and losses we've had this season. You can see it in the data as well as with your own eyes.
As for the players, there are two cases: changing personnel and improving incumbent players.
The personnel changes have been a resounding success; not one poor signing. In a typical starting XI this season, who has remained: Pickford, Keane, Coleman, Gana, Walcott. Keane vastly improved. Pickford still performing at a high level. The rest as last year, if not arguably a bit better. Coleman a special case.
The turnaround in atmosphere, performance, threat, and entertainment in just 16 matches is beyond what we would have expected at the start of the season. I'm not saying there are no negatives. There are. But the future of this team -- players and management -- is something to be very positive about at long last.
