Re: I would be stunned if it's WR

I believe you are right.
The consensus 4th, 5th and 6th rated receivers will likely not carry a higher grade or maybe even be quite as sure a pick short term or long-term considering so many fickle returns on NFL rookie receivers.
So yep a OL or LB could be taken or an edge player to hedge against Quinn and Barwin, and maybe Westbrook Lol.

The spot also might lend itself to a pretty darn good Safety or corner of course.
No denying that.
