NBA Sharp Report: Pros Betting Pistons-Cavs, Knicks-Raptors Monday Night

March Madness is sucking up all the oxygen in the gambling atmosphere, and rightfully so. But wiseguys aren't aren't taking a break and waiting around for the NCAA Tournament to begin. Tonight, they're going where the action is … the NBA.

After analyzing Monday’s 9-game slate using the betting tools available at Sports Insights and The Action Network, I’ve identified three games receiving attention from professional bettors.

Betting Terms to Know

Steam Move: Sudden, drastic and uniform line movement across the market caused by an overload of sharp action from respected players.

Reverse Line Movement: When the betting line moves in the opposite direction of the betting percentages. It’s a top smart money indicator.

Line Freeze: When one side is getting heavy betting, but the line won’t budge, indicating sharp liability on the other side.

Juice: The tax or commission that bettors must pay sportsbooks in order for them to accept your wager. A -115 juice means a bettor would have to wager $115 to win $100.

Detroit Pistons @ Cleveland Cavaliers

7 p.m. ET 

Sharp angle: Under (moved from 213 to 210.5)

Casual bettors are torn on this over/under, but wiseguys have taken a clear side.

The total opened at 213. Currently 52% of bets and more than 90% of dollars are coming in on the under, indicating a slight public lean but also heavy smart money.

Wiseguys got down hard on the Under 213 and Under 212, triggering a pair of steam moves that forced oddsmakers to drop the line down to 210.5. We haven't seen any conflicting signals (or over buyback).

Sharps love this under not only because of the matchup, but also because Detroit's leading scorer Blake Griffin (24.7 PPG) is sitting because of rest.

March is also the best month for betting NBA unders. According to our Bet Labs database, unders in division games have won at a 54.6% rate (6.6% ROI) since 2005.

New York Knicks @ Toronto Raptors

7:30 p.m. ET 

Sharp angle: Under (moved from 214.5 to 213.5)

Pros and Joes will be rooting for opposite sides of this Atlantic Division total.

The over/under opened at 213. Early public over betting (61%) pushed the line up to 214.5. That's when wiseguys hammered the under, triggering market-wide steam that dropped the total down to 213.5.

The under is receiving only 39% of bets but 63% of dollars, further evidence of big pro wagers banking on a lower-scoring game.

Another bonus for under backers: Kawhi Leonard is out tonight (27.1 PPG) and Kyle Lowry (ankle) might sit as well.
