Hey everyone,
I can't seem to find any information about this. Right now and in previous NBA 2k's, the computers defenders defend by position. 
EX:
Cleveland                            VS                            GSW
                                    Defends/Guards          
PG: Kyrie                                                         PG: Curry
SG: JR Smith                                                    SG: Thompson                       
SF: LBJ                                                             SF: KD
PF: LOVE                                                          PF: Green
C: Thompson                                                     C: Pachullia
When we see the NBA Finals, we see Klay guarding Kyrie. We see other scenario's like this all through the history of NBA. San Antonio used to place Bruce Bowen on CP3 and now do it with Danny Green at times.
In NBA 2k17, I don't ever get the CPU's best defender guard my best scorer. If I get hot with one player, I see double teams, but never having the best defender guard me unless we play the same position. Often times to counter this issue, I control all 30 teams in MYGM/MYLEAGUE and have defensive settings for each time I play against to have there best defenders and realistic defensive strategies input into the game.
My question is: will NBA 2k18 finally have something like this built into the A.I? Will Kawhi Leonard finally guard Russell Westbrook automatically in game 6 of the Playoffs? or when Russell scores 20 points in the first half, will the CPU put Danny Green/Kawhi on Russell Westbrook? etc etc...
