This feels like both recency bias and fantasy football mindsets all at once. If you're not filling the stat sheet, you're already a disappointment.
The fact that half of the list is receivers should be telling. Last year's crop of rookie receivers did things that no other rookies have ever done. It was a total fluke, and will probably never happen again. Heck, Julio Jones had just a hair over 50 catches his rookie year; Demaryius Thomas only had 22, and Antonio Brown a mere 16!
Also, something tells me the guy who wrote this list (really, Rant Sports?) has watched maybe 1 or 2 of these players actually play a single football game, and is otherwise just depending on a tiny sample size of statistics to make claims about their performance. With the way every single profile is written ("he's been average against the run, bad at getting pressure"), it seems to me like he's using PFF statistics. You know, the website that said Aaron Rodgers had a bad game on Monday night.
And, yeah, glancing really quickly at PFF's similar piece, that seems to be the case:
