Best Underdog Picks for Sunday, March 22
Use these March Madness DFS picks to guide your lineups on one of the top DFS sites. Fill in your picks to maximize your potential today.
Denzel Aberdeen Higher Than 13.5 Points
Denzel Aberdeen, a key transfer from Florida to Kentucky, has been scoring consistently, averaging 15 points over his last 20 games and logging heavy minutes. Against a tough Iowa State defense focused on Oweh, Kentucky will rely on Aberdeen to step up, and he looks poised to deliver around 13 points.
Ja'Kobi Gillespie Higher Than 5.5 Assists
Ja'Kobi Gillespie has been Tennessee’s offensive engine, averaging 17 points and consistently creating opportunities for teammates, including six assists in six of his last 10 games. If he maintains that production against Virginia, expect him to score and set up multiple baskets, continuing his dominant all-around impact.
Brayden Burries Over 16.5 Points
Brayden Burries leads Arizona’s balanced offense, averaging 18.6 points and shooting 38% from three while scoring efficiently at all levels. Against Utah State, he looks poised to stay hot and deliver 17+ points to help the Wildcats reach the Sweet 16.
