Tanganga is a good example. From looking an absolute liability under Edwards, he is now one of our best players in just two matches! He can't have improved that much himself, it's obviously the change in manager that has helped.
Leaving personalities aside, it's clear that the players weren't capable of executing the passing game that Edward wanted. Passing across the back four (or five) might look good, but it's a recipe for disaster when player are not technically or mentally good at it.
The results of the Edwards experiment are clear for all too see.
