The tone on this board always seems to be that PP failed because of GDL. I hope I am just mis-reading that sentiment. Even if PP fired GDL two years ago, PP still would have been a complete disaster.
To me, GDL was not the cause of PP's downfall, it was a symption of the problem with PP (he was set in his ways, was not willing to change or consider alternatives to what he succeeded with 20 years ago, and hadn't evolved with the game over the past 10 years). While GDL was a complete failure, I feel like he gets too much of the blame for the downfall. Again, he was horrible...but I feel like he was a symptom of the problem, not the problem itself.
