Between Jerry Jeudy, Lamp, Higgins, Pittman, Claypool, Edwards, Proche, Mims, Duvernay, Aiyuk and Reed you might be able to get a good WR in the early 3rd round. But from that list not everyone is a true #1 outside WR. Lamp and Jeudy are more that slot type of player and are only ~ 6 foot tall. Higgins, Pittman, Claypool, Edwards and Mims are possible #1 WR that are some kind of "freakish" espacially Higgins Pittman and Mims look really fast. I wouldn't be surprised if one of them or even two get a 4.40 40yard time.
I would argue that maybe Collin Johnson or Antonio Gandy-Golen are possible guys to look at in the late 3rd early 4th round as well both 6'4/6'5 and both around 4.50.
But again, I'm for buidling from the trenches or BPA expect for QB, K, LS, P we can take anything in the first 3 rows, wouldn't even mind for a qb in the 4th
