Watch: Cooper Kupp showed off his arm with a flat-footed 50-yard bomb

Cooper Kupp makes a living catching passes but he can apparently sling it, too. The All-Pro receiver has quite the arm, showing it off during warmups on Saturday before the Rams-Texans game.

He stood at midfield and launched an absolute bomb to the end zone, sailing it 50 yards in the air. What makes it more impressive is he was standing flat-footed, so it was all upper-body strength from the Rams receiver.

Even Matthew Stafford had to be impressed by Kupp’s arm strength because there probably aren’t many receivers who can launch a ball that far while standing flat-footed.

Kupp stepped back about 5 yards and heaved another pass Stafford’s way from about 55 yards, a perfect throw from No. 10 to 9.
