People, as much as I want to give McHale his props ... be honest, he didn't really create his own shot. He was a part of Bird's overall system.
If Bird and a mature Olajuwon had played together ... forget it! The '86 Celts would only have needed Parish off the bench, along with DJ, Ainge, Wedman, and Sichting. Walton may or may not have needed to contribute much.
That would have won a title, as Olajuwon with a constant double team down low, would have set up Bird to completely destroy any opponent out there, outside or inside.
