No, the big difference is that Wallace is 100 times the deep threat that Hartline is. No one is afraid of Hartline as a deep threat. You'll never see a CB bailing with a Safety over the top against Hartline. Against Wallace? This is standard. Wallace isn't a top-5 WR, but he's a top-3 deep threat. Hartline is not a deep threat. D's dare Hartline to beat them deep.
Hartline is too a deep threat. why do you think they completed that sideline throw so many times. The coverage was loose cuz hartline can get behind you.
If wallace is so much more of a deep threat, then how come harline caught twice as many deep balls as wallace, 10 to 5 hartline wins.
