It seems that Mansion is primarily an exchange that happens to have a sportsbook, and that WSEX is primarily a sportsbook that happens to have an exchange. Is that an accurate statement? I just visited Mansion for the first time, and it looks sweet. Another question is why would anyone play in the sportsbook at Mansion? Can't you get a better line every time from the exchange? On WSEX, do they only offer exchange betting for futures and live betting, or do they do it for every game like Mansion does? I have noticed future lines at WSEX sportsbook, but wondered why they even hang those lines, because for every one, you get a better line on their own exchange. Thanks in advance.
