Finnebaum is an interesting "character" if you will, as an "analyst". His history is enlightening, some radio show which is/was unlistenable bounced up by EPSecN to someone "in the know". He likely does have some connections, for whatever that's worth, and he knows he has to come out with striking opinions to get noticed, and he plays that card effectively.
Does he really know more about who is going to be good than anyone else? Maybe, I'd guess not. I think the Vegas lines are the best predictor we can have, and they are not perfect of course. I occasionally check SECN to see what is on and have listened a few minutes to his "radio show", on TV. It's garbage.
There is a lot of money to be made obviously pretending to be "in the know" on TV.
