Top NBA and NFL Christmas Day picks 

One leg of the five-way parlay that the model recommends is the Philadelphia 76ers (+3) to cover against the Heat in an 8 p.m. ET start on Monday. These franchises know each other well, having met in the 2022 Eastern Conference semifinals (Heat 4-2) in addition to playing three times last season and four times in 2021-22.

It's a matchup that has favored the road team recently, with the visiting side winning and covering the spread in each of the last four head-to-head meetings. The 76ers have also been the more profitable squad against the spread by a considerable margin this season, going 18-8 against the number while the Heat are only 11-16.

Joel Embiid (ankle) has been ruled out for the Sixers, but that has also moved the line 4.5 points, giving Philadelphia some room to work with. Tyrese Maxey is playing extremely well right now, scoring 29 or more points in this last three games. SportsLine's model sees this game coming down to the final possession, making the underdog 76ers the better value play against the spread. See who else to back right here
