Some suggestions to the Vegas functionality.
1. It would be great if this were somehow actionable. It would be cool to wager game credits (not really real money) on whether I -- or anyone else-- is going to make the spread or the O/U.
2. Tournament Pool. This is at the core of what college basketball is all about. It would be fun to have an in-league tournament pool for the NT. I think everyone in the tournament would participate, and it would be a fun way to stay engaged with the league when your team doesn't make the tournament. Doesn't have to be wagering, maybe the people that come out on top just win extra game credits or recruiting points. I think this would increase engagement, retention and most of all fun.
3. I would love to be able to see long term bets. Again to the notion of winning game credits or wagering them-- but also just for fun-- it would be cool to at the beginning of the season see a 'news' article on who is favored to win each conference or become the national champion. It would be fun to be able to make "bets" as to who is going to win a division or even just to follow the movement of the lines over the course of the season.
4. Similar to RPI ratings, it would be fun to track which users in your league are the best at predicting who will win games.
