This argument is laughably. First the discussion is top 5 not top 10. You trying to move the goalposts to make your argument appear more reasonable.
Second, it is 2019 not 2015. Touting his 1,400 yard season which thus far is his only season over 1,000 yards is laughably. Every single one of those guys you mentioned have multiple 1,000 yard seasons not just 1.
WRs with more thousand yard seasons than ARob that are still good - MThomas, Hopkins, OBJ, Hill, Julio, Cooper, Edelman, Landry, Allen,
Young Guys who have surpassed ARob this year - Godwin, Moore, Golladay, Chark, Sutton, Gallup,
Guys who missed time but considered better - Adams, Hill
Now you can quibble with some of those names but I would challenge anyone that is going to pretend that out of those 17 names, ARob somehow is in the top 5. Get real.
Great it is perfectly fine if you want to put him in that company. So long as you understand that stats also put him 20th in total yards and 25th in yards per game. Your problem is you want to cherry pick a stat that suits your argument. ARob is a low end No 1 WR at best. He is nowhere near the top 5.
