A week of good or bad matchups can make all the difference in Fantasy basketball. And before you make any kind of claim on the waiver wire or set any lineups for Week 13, you need to see what 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 can spot an edge in a matchup or identify a player in position to break out, it's him.

Now, Barner has studied the upcoming NBA schedule and is sharing his best and worst matchups for Week 13 of Fantasy basketball. They'll help you figure out who to sit, start, add, and drop this week. 

One thing we can tell you for this week: Barner is giving a boost to several San Antonio Spurs players because of their upcoming schedule.

"The Spurs could be in for a big week with three of their four opponents ranked inside the bottom-half of the league in defensive rating," Barner said. "That could mean plenty of juicy stats on the horizon for DeMar DeRozan and Dejounte Murray, although you will need to monitor for updates on DeRozan, who was set to miss his second straight game Sunday because of personal reasons. With LaMarcus Aldridge now sidelined while the team works on trading him, Keldon Johnson, Jakob Poeltl and Rudy Gay all have starting upside in Fantasy, as well. Finally, despite his inconsistent play, Derrick White warrants starting consideration. Even though he's only shooting 39.4 percent from the field, he's still averaging 11.7 points and 1.7 three-pointers."

Barner has also identified a sleeper who NEEDS to be in your lineup this week because of a favorable schedule. This player should return massive Fantasy numbers in multiple categories, and he's most likely on the waiver wire in your league right now.

So who should you start and sit this week? And which overlooked sleeper could lead your team to victory? ... Join SportsLine right now to get Mike Barner's best and worst Fantasy basketball matchups for Week 13, all from one of the most respected voices in the industry!
