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 recently been nominated for an FSWA award for Basketball Writer of the Year. 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 Fantasy basketball matchups for Week 25. They'll help you figure out who to sit, start, add, and drop this week. One thing we can tell you for Week 25: Barner loves the matchups for the Utah Jazz, a team that has four games on the schedule and is still battling for playoff positioning. 

"The final four teams in the Western Conference are virtually locked in, but the fifth and eighth seeds are only separated by two games in the loss column," Barner said. "The Jazz are in that group, so look for them to deploy their normal rotations this week. That's excellent news considering three of their four opponents are inside the top-12 in the league in pace of play. Donovan Mitchell, Rudy Gobert, Joe Ingles, Ricky Rubio and Derrick Favors should all be locked into Fantasy starting lineups. Jae Crowder was only started in 26 percent of CBS leagues during for Week 24, but he's also worthy of a starting spot after averaging 12.8 points, 5.1 rebounds, 1.1 steals and 2.2 3-pointers across his last 13 games."

Barner has also identified a playoff contender that has an extremely tough week of matchups coming up. Players from this squad could be in line for a disappointing week, so you absolutely need to see his breakdown.
