There is a very strong argument to be made that Hurns (2/12) is a better receiver than Richardson (5/40). Richardson was basically written off as a bust until last season, putting up only 51/559/2 in his first 3 years combined, although to be fair he missed basically all of 2015. With that said, about 250 yards and 1 TD per season is not great.
Of course Richardson had a nice 2017 with 44/703/6, although Hurns had a roughly equal rookie season statistically (51/677/6), a far superior season in his 2nd year (64/1031/10), and then the last two seasons he missed several games but was still roughly on pace to statistically match Richardson's career year (Richardson averaged 43.9 YPG last year, Hurns averaged 43.4 in 2016 and 48.4 last season).
And Richardson had Wilson while Hurns was playing with Bortles.
In short, fuck the Redskins.
