False. Cooper is better. Not the better career, but he's the better player right now. Let's use just last year for comparison:
2017 Dez: 69 catches, 838 yards, 6 TDs, 12.1ypc, Eight 20+ yard catches, Two 40+ yard catches - 16 games played
2017 Cooper: 48 catches, 680 yards, 7 TDs, 14.2ypc, Nine 20+ yard catches, Three 40+ yard catches - 14 games played
Give me the receiver who is almost 6 years younger, more explosive, way faster (4.4 speed), runs better routes, and has the better catch radius. Sorry, but 2014 Dez is long gone. And Cooper has his prime years in front of him.
