I'll wait for you to find another individual with full personnel control who has won more Super Bowls.
Bill had full and complete personnel control from 2000 to last year. Won 6 Super Bowls. He made final decisions on free agents, contracts, the draft. Players and agents negotiated with him directly.
This is not a controversial statement at all. He is the greatest GM in NFL history. If results matter to you, it's not close.
