I know many on this board (myself included) really liked aspects of Grantland. Think what you will about Simmons and shark-jumping, but that website produced a lot of really good reads on sports and other stuff (and yes, it produced some crap). I thought it was great that so many younger writers were given free reign and did well. I never thought I'd be reading MTVNews, but so many former Grantlanders whose work I enjoy eneded up there.
Simmons didn't get the whole band back together, but his new website https://theringer.com/ is now live. It looks like most of the content isn't sports related yet (EDIT: The current main article is politics related, FYI), but it'll be intersting to see where this goes.
