Pound 4 Pound the GOAT 'staredowner' ever is Gary "The Rocket" Lockett aka Agent Smith. He will make OP baby cry.
Hearns-Benitez was real good too. As was Foreman-Lyle. Tyson rarely got into pre-fight staredowns, but the one with McNeeley was memorable. Trinidad-Vargas, although my Spanish is limited and I don't know what Tito was saying.
