He has 535 through 22 games. CSKA Moscow's Nando De Colo set the record with 656 in 27 games two years ago in his MVP season. If he averages 15.2 over the eight remaining regular season games – or even 11.0 with three playoff appearances, should Madrid qualify – Doncic will take the record.
Doncic's average index rating of 24.3 is the third-highest ever among players with a minimum of 20 appearances, but he will have to raise it to surpass the top two: Maccabi Tel Aviv legend Anthony Parker (24.9 in 2004-05) and Crvena Zvezda mts Belgrade center Boban Marjanovic (25.7 in 2014-15).
Doncic is also in the record hunt for best per-minute index rating. His average of 37.3 prorated over 40 minutes trails only Marjanovic's 37.6. In third place is Hall of Fame center Arvydas Sabonis of Zalgiris Kaunas (37.2 in 2003-04).
Doncic could also set the EuroLeague record for three throws made in a season, which is 168 by Langford for UNICS last season. Doncic has made 114 so far, which is an average of more than 5 per game and on pace for 155 at the end of the regular season. At that rate, Doncic would take the record in the playoffs.
Similarly, Doncic has the inside track on Lanford's record of 202 free throw attempts in a season. With 140 attempts thus far, he is on pace for 191 for the regular season alone.
