Yeah, not sure I get this. The first rounders aren't working out by some measures, but one of the greatest WR drafts happened just a few years ago in the far off time of 2014.
Odell, Mike Evans, Brandin Cooks, Sammy Watkins, and Kelvin Benjamin in the first round alone. After that, you have other notables like...
Marquise Lee, Paul Richardson, Jordan Matthews, DeVante Adams, Allen Robinson, Jarvis Landry, Donte Moncrief, John Brown, Martavius Bryant, Ryan Grant, Quincy Enunwa, Willie Snead, and Allen Hurns.
Some of those later guys have only shown flashes or have had derailments due to injury, but that stretch from DeVante to Landry is three pro bowl receivers on day 2 picks. That first round is impressive. Name another time 5 players were picked from the same position group in the first round, and they all worked out as well as that. Benjamin is the disappointment in that bunch and he still has potential to be a 1000 yd guy. It's odd that they put their cut off right after 2014.
And some of the guys they bring up are rookies who had injuries like Corey Davis, John Ross, or Mike Williams. To bring up rookies in the first place is ridiculous, but to bring up those with injuries is doubly so. How does bringing up injured guys indicate a crisis at the position and how it's taught? That doesn't back up the argument they are making.
I remember when people were giving guys 2-3 years at the receiver spot to break in and now it's instant gratification. The same thing happened with QBs after Luck, RG3, and Wilson hit it big their rookie years and subsequent draft classes were and have been looked down upon since then. People need to readjust themselves after a big rookie position class hits the scene and stop thinking that it's always the norm for guys to come in and put up Odell or AJ Green numbers in year one.
