Here's another good highlight video for those who are interested:

I'd be okay with picking him here because I do think you are probably getting a low risk Pro Bowl quality player here.
He should probably get 5-10 touches a game returning alone. Maybe 3-5 rushes as well out of a 0 back set with 3WRs and 2TEs with Tavon flexing into the backfield and the 2 TEs blocking inline against a dime defense with only a single LB. Then you should be able to get the ball out to him 3-6 times a game as a WR. That looks like about 15 touches a game. He'd be getting the ball more than anyone not named Murray.
There are a couple of things that sell me on this as a pick if he is on the board and Cooper is gone. One is that he makes premier players in college football look downright silly on the field. It also isn't a thing where they get used to it either - he does it over and over again. He is just too quick with his cuts and has too much speed for anyone to tackle him in the open field. They need a whole group of guys to corral him anytime he gets in open space. The only guy who I saw who could do this was Barry Sanders. Raghib Ismail was more of a pure speed player and never quite had these kind of cuts. Reggie Bush would also be a consideration but he also didn't have quite the same cuts and relied more on pure speed. Another area where he appears to be special is his ability, willingness and toughness to actually turn it back into the middle of the defense. People his size just aren't supposed to be able to do that and yet he can. I don't know much about his hands since it looks like hardly any of his catches are contested but he seems to catch the ball very cleanly on passes and in returns.
Right now it looks like most people having him off the board by our pick but sometimes these luxury picks can drop a bit. If we take him in the first it has to be with a commitment to run an offense where he plays 70% of the snaps and would signal a dedication to using 3 WRs as our base offense. I don't want us to draft anymore backups in the first two rounds and right now Miles and Dez are the starting WRs and they look to be set in their roles for the next two years. I really do think adding his speed to the WR core would be a major addition as Dez and Miles don't stretch the defense in the same way Tavon could - if he's even with you then he's leaving you. It is really incredible to see him outrun the angles DBs take on him.
