There's been a recent trend circulating around the NBA in recent years. Resting players has become a common occurrence around the final stretch of the regular season, and it would be wise for the Raptors to follow the trend.
It started out in 2012, when Spurs coach Gregg Popovich decided to rest his top players in a marquee matchup out of nowhere against the Miami Heat. San Antonio and Pop got fined for that decision, but other teams still took a page out of the Spurs' book and this has become a regular occurence in the League today.
