Van Jefferson is no #1 WR, IMHO. Come Sunday, at Seattle, no less, the Rams will be trotting out old man Stafford with a suspect OL, an average running game, and a #2, #3 and #4 WR miscast as #1, #2 and #3.
Just my opinion but good luck with that.
Yes, a #1 WR in a bad offensive situation or varying degrees of suboptimal QB'ing is still a #1 WR, but there's a big difference between Drake London and Michael PIttman, and bigger difference between Michael Pittman and Van Jefferson.
I'll pass, but that's just me.
