My first thought upon reading this was a member of a fired staff setting the bar artificially high for the new staff so it's tough for the new staff to look successful. A touch of sour grapes, though I don't think that's really Busch's character.
Then he said this and erased that negative spin I had in my head:
"I feel that there is good leadership now that took over talent and brought in more talent."
Pretty telling because he's basically dumping on the staff he was a part of, but good for him for being objective.
