Some get wrapped up with 40 times thinking it's the real measurable for the skill position players. There is a real difference between someone's true speed and football speed. Most guys aren't going to be running 40 yards at full speed unless it's a break away. There have been many great players who weren't lightning fast. It's how a guy can create separation while running his route which is more important, because not all routes are going to be a "go" route. If you watch his hi-lights, he does create separation, and has the speed to extend plays. He's not going to be just a possession receiver. He will stretch the field when it's needed, and tough enough to catch a pass in traffic too.
