Pascal Siakam, a major contributor in Toronto's run to the NBA title last season, has signed a four-year maximum rookie contract extension for $130 million, according to multiple reports Saturday. The 25-year-old Cameroonian forward signed the deal ahead of a Monday deadline for such extensions for 2016 draftees, ESPN and the Toronto Star reported. Siakam was voted the NBA's Most Improved Player last season as the Raptors, powered by Kawhi Leonard, captured the NBA title, defeating defending champion Golden State in the final.
