The position eligibility of K.Irving should be "PG/SG"
After the trade including James Harden, Harden is playing as a primary playmaker and a ball handler of the BKN best lineup.
And Irving puts all his energy into the scoring.
When it comes to this issue, Irving said that he is a shooting guard.
For more detail, please refer to the link I have given below.
Therefore, I think K.Irving should have SG position eligibility at this point.
Thanks for consideration.
