There's been some well documented complaints from fans who use SB Nation/WAGNH on their phones recently regarding comments not showing.
Well, lo and behold, somehow I stumbled upon an answer.
I was using Opera Mini on my Nokia C2 (stop laughing!), and was browsing WAGNH in the morning, as I usually do, and I opened up an article. However, I did something different. Rather than clicking on the title of the article, I clicked on the number of comments/unread comments (to the top right of the article name if you're on Mobile View, otherwise in the normal position where it'd be on the normal site).
Voila! You can now read comments with the article!
