Cavaliers vs. Pistons

7 p.m. ET

The sharp angle for tonight's Cavs-Pistons has been about as obvious as it gets.

For starters, the line has moved pretty significantly against a heavily popular bet. The total has fallen from 221 (and even 223 at the earliest books to open) down to 218.5 despite 71% of bettors taking the over, which should tell you something about the 29% taking the under.

That 29% has generated 56% of actual money hitting the total, and while that doesn't create a huge monetary liability by any means, it does reveal that those bettors are making much bigger bets — the ones more likely to come from sharps.

Confirming the pro action, five Sports Insights Bet Signals — indicators of market movement caused by sharp activity — have hit the under at lines ranging from 223 to 219.5, bringing the market to its current number.

Spurs vs. Bulls

8 p.m. ET

Following the afternoon announcement of LaMarcus Alrdrige's absence for tonight's game, the minus sign on the spread flipped over to the home team. And while sharps may have been leaning toward Chicago anyway, the cause of the line move is a bit tougher to judge given the timing.

As for the total, however, it's been steadily decreasing throughout the day, and has even continued a bit since the Aldridge announcement.

Unlike the game above, this one has sharps and public bettors in agreement, as 60% of bets have landed on the under. Like the game above, though, those bets have been of the much bigger variety, this time generating a whopping 93% of bets.

Once again, Sports Insights Bet Signals have triggered five sharp move on the under (between 218 and 214.5), explaining the significant drop.
