The way I see it. I would take BJ over Kirk if I build a team 10/10. He was better on defense, better on offense, better as a PG, and better off the ball, prime vs prime. He would have been a Bull until retirement if it wasn't for that BS expansion draft.
Rose
Norm
BJ
Theus
Kirk
Paxson
And I don't count Harper, as he was merely the PG when you had to write something in on the depth chart, but played less PG than Pippen. This is how you can spot a junior Bulls fan a mile away, they will almost always list Harper.
What I do think is different about Kirk, is that he might see his number retired for many unusual reasons and maybe pax's crush on him. Which IMO is amazing, none of the top PGs have retired numbers(unless you count MJ and Pip who did play that role for a few seasons each, easily). Rose's MVP should get him there, but if the team and rose part ways under some ugly conditions, who knows. Just something that may become a reality in Kirk being the only one.
