I can tell you this, he was stunned in the end to hear from so many people sending him good wishes on his facebook page.
What we know and what many in radio management forget at times is all talent feel as valadated as their current job. Sure he was brand, sure he moved the meter, and sure we all wish he had better control of his addiction issues earlier, but you take a guy like that and let him get unreturned phone calls from current pd's who have some better idea that is THEIR idea, and the years of impact start to feel like "did anybody notice and will anybody remember?"
radio talent, like recording artists, sometimes feel empty when their alterego isn't able to perform.
It's what he did. It's what gave him life. And he like many, missed that in the end.
