Sonny Bill Williams says Logan fighter Alex Leapai Junior has the raw power and the boxing pedigree to be a star on the global stage, as the boxer prepares to step back into the ring Wednesday night. Leapai Junior, whose father Alex Leapai Senior was once a world title contender, will don the gloves as a professional for a sixth time this week in the undercard for the Williams bout with fellow former rugby league player-turned-fighter Paul Gallen. But Williams’ connection with the Leapai clan began many years earlier. Ahead of his high-profile clash, the dual-rugby code star recalled to this masthead a sparring session with Leapai Senior about 16 years ago. And he believed Leapai Junior had the tools to go where his dad fell agonisingly short.
