ASHBURN, Va. — The Washington Commanders added needed depth at wide receiver with the signing of Stefon Diggs. They agreed Wednesday to the deal with Diggs, who could practice for the first time with his new team Friday. 1 Terry McLaurin, ending a lingering process to get quarterback Jayden Daniels some more pass-catching help. Pairing Diggs with McLaurin gives Washington arguable its best wide receiver duo since Pierre Garcon and DeSean Jackson each topped the 1,000-yard mark in 2016. The Commanders are Diggs’ fourth team in as many years, but the 32-year-old showed last year he has plenty in the tank.
