I doubt he will. He tore his ACL against Georgia.(final game of the regular season for GT)
But I can see on film that he's fast. Plus, check out his hips here:

Look at how fluid they are on the hitch and go. He makes it look easy when most 6'2"/6'3" 220+ pound WRs struggle sinking their hips into the hitch and then exploding out of it to the go like he did.
He has tremendous flexibility and fluidity in his hips and body overall. He accelerates quickly off the LOS, has impressive top-end speed, MASSIVE hands, and is very physical while running routes. He bullies defenders and is not afraid to push off. Which I like. You can always reign a big guy in on pushing off but it's hard to instill that sort of aggressive, bully mindset in them if they don't have it.
To put it bluntly, Smelter is a freak. If he hadn't torn his ACL, I'd be saying that we need to trade down and take him in the first. Because IMO, he would have ran in the 4.38 to 4.45 range at the Combine. He's faster on tape than Waller.
