Market Insights: What we've learned from NBA first half

We've reached the unofficial halfway point of the 2019-2020 NBA season with most teams sitting at roughly 41 games played out of the 82-game regular season schedule. The All-Star Break is still a month away (Feb. 14-16 in Chicago), but now is a good time to reflect on first-half trends, including what systems, teams and situations in particular have been beneficial for NBA bettors.

Before diving into first-half betting results, let's discuss a quick update on a pair of meaningful line moves for NFL conference championship Sunday. 

Titans at Chiefs: This line opened with Kansas City listed as 7.5-point home favorites. The public is all over the Chiefs with two-thirds of bets laying the points. All week, this line has remained frozen at 7.5. The fact that oddsmakers refused to raise it to 8 despite the lopsided Chiefs betting signaled sharp liability on the road dog Titans. Yesterday we saw sharps make their move on Tennessee, hitting the Titans plus the hook (+ 7.5), moving the line down to 7. We now have a true sharp reverse line move on Tennessee plus the points. 

Playoff dogs that see the line stay the same or move in their direction (think + 7.5 to + 7) are 3-1 ATS this postseason and 59-42 ATS (58%) since 2003 according to Bet Labs Sports. Big playoff dogs of + 7 or more are 37-26 ATS (59%), including 6-2 ATS in conference title games. Jimmy Vaccaro took a $44,000 bet on the Titans + 7.5 at the South Point yesterday. 

Packers at 49ers: The NFC Championship game line opened San Francisco -7, quickly moved to -7.5 and hasn't budged since. However, the over has taken in sharp money over the last 24 hours, rising from 45 to 46.5. AFC and NFC Championship overs are 18-11 (62%) since 2003. The weather looks perfect for Sunday with temperatures in the high 50s, overcast with little-to-no wind. 

Friday's action features 7 NBA games, 3 NHL games and 9 College Basketball games. For an updated breakdown of sharp action across the marketplace be sure to tune in to the VSiN Market Insights Podcast with Josh Appelbaum. It will be posted at 3:30 p.m. ET.
