The Minister of Defense is back for the Orlando Magic. Using data from both his 2022-2023 season and his previous season of 2019-2020, here is a piece of advanced stats knowledge to show how Jonathan Isaac has earned the nickname.
In this current 2022-2023 season, the top five DRtg Leaders in the league include players like Steven Adams, Joel Embiid, and Giannis Antetokounmpo. They are doing it with DRtg figures from 106 to 107 where the lower the number the better (Criteria: Minimum of a certain number of minutes played).
There are no Magic players with a DRtg of 111 or lower so far this season. And ORL is a dismal 23rd in team defense rating.
In Jonathan Isaac's two games of the 2022-2023 season, he has compiled a DRtg of 95! He has often had the best DRtg of both teams' players to step onto the court in games.

So what exactly is DRtg again?
DRtg stands for Defensive Rating, and it is part of the efficiency metrics developed by Dean Oliver in his 2004 book Basketball on Paper. One way to look at Defensive Rating is in the way it estimates the number "Stops" a player makes while on the court. For Dean Oliver, he gets to the DRtg's final figure with formulas such as;
- Stops1 = STL + BLK * FMwt * (1 - 1.07 * DOR%) + DRB * (1 - FMwt)
- Stops2 = (((Opponent_FGA - Opponent_FGM - Team_BLK) / Team_MP) * FMwt * (1 - 1.07 * DOR%) + ((Opponent_TOV - Team_STL) / Team_MP)) * MP + (PF / Team_PF) * 0.4 * Opponent_FTA * (1 - (Opponent_FTM / Opponent_FTA))^2
- Stop% = (Stops * Opponent_MP) / (Team_Possessions * MP)
- DRtg = Team_Defensive_Rating + 0.2 * (100 * D_Pts_per_ScPoss * (1 - Stop%) - Team_Defensive_Rating)

DRtg is now used as an advanced stat by NBA teams, and can be found and tracked in the biggest NBA websites like NBA.com and Basketball-Reference.com.
Is DRtg fair in a 2 game sample size though?
Well, let's look at a bigger sample size now. In Jonathan Isaac's previous played season, 2019-2020, Isaac played a big 30+ minutes per game in 18 games. In those high-minutes outings, his DRtg was 101. In the entire league, only Giannis Antetokounmpo and Brook Lopez from the same team (MIL) had a higher DRtg.

In the same 2019-2020 season, Isaac also played 12 games for a similar, impactful rotation role; the 20-29 mpg role. In those significant-part-of-the-rotation outings, his DRtg was 99. In the entire league, and you probably guessed who it was by now, only Giannis Antetokounmpo had a higher DRtg.

So maybe Coach Steve Clifford (now with CHA) once compared Jonathan Isaac to a defensive legend in Shane Battier for a good reason. Isaac is after all, the Minister of Defense.
