I have bet 3 of these, and won all 3. I always go large on them, 2 or 3 units, and I'm 3 for 3. Granted it's a small sample size, but I feel like these numbers should always be higher than they are. They should be 19, 20, 21 or so, not 14, 15. The chances that a game never gets above a 15 point difference seems super rare to me. I don't get it, it seems easy but maybe I've gotten lucky. I try to pick teams that are volatile and so far it's worked out great.
Anyone else ever do these bets?
