Four cracked it last year, and Diontae and Slayton came close. He barely even has two cracking 700 yards (Jeudy at 706). Rookie WR's cracking the 700 yard mark have a very good success rate. The 2020 WR class dwarfs that class. It's a totally dismissive projection of the talent in this class.
I was curious about this.
I did a search on rookie WR seasons 1999 to 2019 so we have a

58 times a rookie WR had 700 or more receiving yards.
This is an average of 2.9 players doing this per season.
Knowing this and also with consideration for the quality of WR in the 2020 draft class I would agree that one more WR could have over 700 yards based on this average.
Generally I am on conservative side of expecting great things from rookie players, Maybe I just like to be pleasantly surprised.
I think Lamb and Juedy can achieve this threshold as rookies. Who else do you think could?
