I wish he'd call randomly. Then it would be an exciting surprise to hear from him, but at the beginning of the show Tom gets pumped by good calls, like Hulk Hogan. And Spike is usually pretty hit or miss and usually a long call.
I'm sure that if he started doing the reviews or something it would be better, but if not, maybe just save Spike for the end of the show when Tom has built enough steam to carry the W?
