I'd argue that Golic was less about him being naive, and more about him massively overestimating his standing, and thinking he had juice that he didn't even come close to having.
He really thought that he was the Stephen A of ESPN Radio. Meanwhile, Golic and Wingo somehow managed to be an even older and whiter version of Mike and Mike, and ESPN affiliated sports talk stations have been struggling, since the shrinking audience isn't tuning in to hear national shows at this point anyway. He should've known what time it was when Wingo's primary reason for quitting the show, knowing full well it was probably him actually quitting the company, was "I don't want to get up that early," and there weren't a ton of people rushing to replace him.
