Top DFS app picks for Dec. 20 

One of the top NFL prop picks at Underdog is Packers receiver Jayden Reed going higher than 39.5 receiving yards. Reed has returned from early-season injuries to make an impact recently In last week's 34-26 loss to the Denver Broncos, he caught five passes for 55 yards. SportsLine's model is projecting 55 receiving yards, rating this a 4.5-star (out of 5) pick.

At Betr, one of the top picks is that Commanders receiver Deebo Samuel goes higher than 43.5 receiving yards. He's averaging 52 yards per game his last four outings. With Washington listed as a 7-point underdog, the Commanders might have to throw late in this one, giving him the targets needed to clear this total. The model projects 57.5 points.
