For a foreign owner who readily claimed no prior knowledge of Aston Villa, or it's history, I think Lerner has actually done an admirable job in honoring the tradition and history of the club, and respecting the thoughts and ideas from supporters- from the Holte Hotel renovation, to consulting with supporters over the club crest redesign, to bringing back Ron Saunders to VP, etc. It's fairly clear that he's put in an honest effort to listen and learn about the history and traditions of the club. I don't see how one can interpret things differently. That said, he's stumbled badly the last couple of years.
But his many mistakes have nothing to do with a lack of honoring or understanding the history of the club; it's a lack of nous, footballing nous, and how it's applicable to the business side of running the club.
At this juncture, I'm really far less concerned about the depth of Lerner's knowledge of history than I am with his knowledge of how to operate a successful football club. We were just a few points off a Champion's League birth a few seasons ago and who knows where we'd be now? Lerner gave it an honest go from the start, and made every effort to show due respect for the club, it's traditions and it's supporters. Wasn't that what people were all happy about when he took over?
I'm just not really convinced that you can blame our current situation on his history deficiency.
