Matthew Stafford was in peak form on Sunday, leading the Los Angeles Rams to a 45-17 rout of the Arizona Cardinals. Stafford, 37, threw for 281 yards and three touchdowns, while Puka Nacua and Blake Corum each scored twice as the Rams (10-3) poured in 35 unanswered points to rebound from last week’s turnover-marred loss to Carolina.
