He did a lot of odds stuff for ESPN too. Obviously gambling on sports was big in his life long before it became what it is today.
They've loosened it up hugely and there are shows that outright talk about gambling, but the NFL used to crack down on that stuff really hard, I assume. So, Hank would go on and say things like "I expect the Dolphins to win....and WIN BIG this week." Or, "I expect the Dolphins to win but eek this one out in a tight game" ...basically saying about covering spreads, but his annunciation was kinda cheeky.
But yeah, looking back, his show was for gambling derelicts...he would talk about the Preakness and all that crap. I always hated that.
