NBA All-Star Weekend takes place in Chicago, and one of the highlights of the weekend is the Mountain Dew 3-Point Contest, set for Saturday at 9 p.m. ET.

In an era dominated by the trey, the contest is not short of elite entrants, including Trae Young and defending champion Joe Harris. However, before you make your 3-Point Contest picks, you'll want to see what NBA expert Mike Barner has to say. 

A respected NBA Fantasy expert, both season-long and daily, Barner's work has appeared in Sports Illustrated and on Yahoo, RotoWire and KFFL. He's also been featured on ESPN Radio. Barner digs deep into the data, examining team trends and projecting game outcomes.

Barner's expertise has been on full display lately. He is on an amazing 78-47 run in against-the-spread picks, returning over $2,600 to $100 players.

Now he has analyzed the 3-Point Contest lineup from all angles and is delivering his picks for SportsLine. We can tell you that Barner is not going with Harris, even though he's the favorite at +350. In fact, Harris is barely shooting over 40 percent from 3-point territory this season.

Barner has identified a key X-factor that makes one player a must-back on Saturday. You ABSOLUTELY need to see it before locking in any picks of your own.
