I'd argue he was ahead of his time on sports gambling when you consider how proliferated it has become. Where he always lost me? He was so arrogant that he thought listeners, especially at the end of his tenure, were interested in things like boxing and golf on a network that had juwt won the NHL deal. Why? Because that's what HE wanted to talk about, current sports events be damned. That all said, he consistently had the best ratings of any AM station during key prime hours. It gave him incredible leverage to keep doing whatever the hell he wanted.
The problem was his compensation. He was the highest paid personality at Rogers and that bothered some people high up - when Scott Moore left Rogers, McCown lost his bodyguard. As soon as McCown's numbers started to dip (with Overdrive taking some of the listeners) they couldn't have been happier to get rid of him.
Man just once I'd have like to see the guy thank his producers once. Man was he a prick.
