I'm expecting an intense matchup here as both teams are 0-2 in the reboot and fighting for a playoff spot. So I'll take the points. 
Yes, the Grizzlies played Sunday against the Spurs, losing 108-106 on two free throws at the end. Memphis also fell in overtime to Portland. This marks their third game in four days and second in two days. Perhaps that's why this line is inflated in my view. But the Grizzlies are a young team and have fresh legs following the long layoff. Fatigue shouldn't be a factor this early in the Orlando bubble. The Grizzlies actually have excelled in this situation covering seven of the past eight times they played without rest. 
The Pelicans have loads of talent. But they commit too many turnovers, lack defense, are not well coached and Zion Williamson has had his minutes reduced. Williamson has played just 15 and 14 minutes during the Pelicans' first two games of the resumed season. Not only is this good from an opposition standpoint, but Williamson's lack of playing time has kept New Orleans from finding its rhythm after the long break.
