Without looking at the list I'm sure they have a lot of guys ranked on hype that haven't proven anything in the league. Some of these will develop into stars and some of these will catch less passes than the words in this post in the next few years.
"When the Cowboys selected CeeDee Lamb in the first round of the 2020 NFL Draft, they created arguably the best trio of starting wide receivers in the NFL "
"Ruggs’ production with the Crimson Tide won’t blow you away, but he has the tools to be a complete wide receiver "
That's just two teams. You're right. Projection on what COULD happen. A few things to keep in mind. Miami, a bad team for a long time, gets no pass. Good teams are always assumed to make brilliant picks. Pick the best WR corp in the year and put them on the '19 Fins. Still the best? I'm not going to pretend Miami has a top 5 WR corp, but with (we hope) a much better run game and QB, they won't be 29th
