Quinn Cook has been a remarkably steady fill-in for the injured Stephen Curry, and the Golden State Warriors rewarded the former two-way guard with a new contract Tuesday. The 25-year-old Cook, who has impressed his coaches and teammates with his growth and poise on and off the court, had to sign an NBA contract before the playoffs begin this weekend to be eligible. Going into Tuesday's regular-season finale at Utah, Cook had reached double figures in scoring in 14 straight games.
