At best they'd be looking at Williams for wing, not centre, so Beau Scott wouldn't be keeping him out. Williams would continue the trend of quality NSW wingers of late....McManus, Turner, Quinn.
Outside of Folau and Inglis the Queensland backs aren't massive. Slater, Tate, Boyd, Tonga are no bigger than what NSW could offer up. There are better options than T-Rex on the wing for NSW.
