NFL Week 16 was another wild week for Underdogs, as several Favorites not only failed to cover the spread, but also lost outright.

If you haven't been following, be sure to follow our Upset Watch column, as we went 6-1 last week on Underdog bets, and continue to have an eye for Upsets.

Today is another Tuesday with no NFL, but with packed schedules in the NBA and NHL, there are a shockingly high number of Arbitrage opportunities to build your bankroll with guaranteed profit.
