Finding the perfect addition to your Fantasy basketball team via the waiver wire can be the difference between winning your league or going home with nothing. And before you determine which players you should target on the waiver wire this week, you absolutely need to see what SportsLine's NBA Fantasy expert Mike Barner has to say.

Barner is one of the most respected voices in the industry, whose work has appeared in Sports Illustrated and on Yahoo, RotoWire and KFFL. He's also been featured on ESPN Radio. He digs deep into the data, examining team trends and projecting game outcomes. If there's anybody who knows what it takes to win a league, it's him.

Now, he's revealed the best widely available free agents ahead of Week 18. One player Barner is advising Fantasy players to target on the Week 18 waiver wire: Wizards forward Davis Bertans, who is available in 51 percent of leagues.

"The Wizards play at least four games in each of the final four weeks, so Bertans could provide value in the scoring column from here on out," Barner said. "He's seen a decline in playing time compared to last season, but that hasn't prevented him from averaging 13.7 points and 3.8 three-pointers across his last six games. For those who need 3-pointers, his favorable schedule could not come at a better time."

Barner has also identified which other players you should target on waivers if you need a jolt for your squad, including a forward available in almost 60 percent of leagues who is playing for a team "decimated by injuries." Anyone who adds this player could hit it BIG.

So which players should you target on the Fantasy basketball waiver wire in Week 18? And which overlooked forward could lead your team to victory this week? ... Join SportsLine right now to see the best league-winning free agents, all from one of the most respected voices in the industry!
