I just don't know what has happened in the past 5 years. Up until around 2013/2014, Arsenal were run as well as anybody. Then almost complete collapse. Perhaps it was Gazidis exerting his influence as his power grew, or Wenger getting old and not working miracles? Or perhaps Wenger changed and had so much control himaelf it killed us? Regardless of what caused the shocking decline, to go from where we were in 2013 to where we are now is gross mismanagement.
I can only hope that, given that he's not going anywhere, Kroenke couldn't manouver the club in the direction he wanted and thought was best because he didn't own the club outright and didn't have the authority to sack Wenger or Gazidis, make sweeping changes etc. It's probably wishful thinking, but perhaps things will run differently now the club is his? There has certainly been a lot of changes in the past 12 months, but that could just be the reaction to the decline worsening.
