1. No more Chris Boucher/Precious Achiuwa together lineups.
This is the third year in which Boucher and Achiuwa, who often find themselves playing similar roles, will be on the team together. Nick Nurse wasn't able to fully quit his addiction to putting both of these players on the floor together, and Rajakovic is falling for this trick as well.
Per Cleaning The Glass (subscription required), the Raptors are 6.1 points per 100 possessions worse than their opponent in all lineups with more than 20 possessions on the floor that feature both Achiuwa and Boucher together. The Malachi Flynn-Jalen McDaniels-Scottie Barnes lineup alongside those two grades out as one of the worst lineups in the NBA.
Chris Boucher and Precious Achiuwa can't play alongside one another.
Masai Ujiri shouldn't be faulted for believing this could work. The slender veteran Boucher and athletic freak sparkplug in Achiuwa may seem complementary, but they both offer little value as volume shooters and lack the size needed to truly hold their own at center.
By the time the trade deadline passes, it seems increasingly unlikely that both of these players will be on the team together due to overlapping skill sets. The sooner Rajakovic realizes that these lineups simply do not work, the better the offense will be.
