Benji Marshall for sure, like Gasnier and Bowen rely as much on their speed as their step, but Marshall isn't that quick but his step is awesome. After watching last nights game I reckon David Faeimu has probably got the best footwork for a forward. Also someone who's abit forgotten about is Willie Tonga.
AND BBSF, Covell best footwork in the game? He's got as much footwork as Shane Webcke.
