I have been watching with some entertainment the way this story has developed since it was originally mentioned. I was going to comment on it but Jim Michaels got there ahead of me. Anyway I think it is interesting and possibly a good commentary on going back to the source to find out what they actually said

To clarify, before I get in any trouble with the writers, on this here fair website: For the likes of us on here who come to glean every bit of news out there the Spoiler pages commenting on this are GREAT and Lilah and Percysowner, to name but two people involved in getting this information, do a wonderful job. We see that it is just speculation and may or may not happen but here is what the general public and casual (female*) viewers got by way of a story this past few days

“One thing we’ll add here: It’s too bad that Stephen Amell is so busy with “Arrow.” Given his performance recently in the tag-team battle against Stardust, wouldn’t he be more than capable of taking on one of these roles?”

“The tweet could mean a million different things — or even nothing at all. Still, let your imagination run wild for a moment and hope that it’s a bit of a tease about what’s to come from the actor and the show."
Day 2
International Business Times: December 30 2015 4:43 PM
“As for the casting of wrestlers in “Supernatural” Season 11, a Zap2it report has listed down a couple of reasons why “Arrow” actor Stephen Amell could portray the role in the CW TV series. The report noted down that Amell is a fan of “Supernatural,” which also films in Vancouver ... “

Day 5
[i]The Hans India January 02,2016, 02.21 PM Headline: Stephen Amell to guest-star on 'Supernatural'
"Arrow’ star Stephen Amell is expected to make a guest appearance in an episode for the upcoming season 11 of ‘Supernatural’. "

"{I am not going to include their @ in case they don't want the attention}
"Let Amell do his arrow thing please! We don't need him on spn @TheJimMichaels"
A little ungracious perhaps but a valid comment under the circumstances:
Here is the reply:
Jim Michaels
If you cant read that it says
Jim Michaels @TheJimMichaels: "Steve is a great guy but have no idea where this rumor started"
So there you go. How to start a rumor that will puzzle a show's producer ...
Of course none of this discounts the possibility that all of this has been a stealth advertising campaign, or Stephen really would like to be on SPN, or that it might happen since there is so much interest, but the way the story developed is pretty interesting.
