The media guide itself hasn't been posted yet, but you can see most of the media guide photos and bios at soberkeley.com.
Use the "meet the team" drop-down menu at the top. After clicking on a player's name, note that the next page will have two links. The first (e.g. "Afure Jemerigbe") will lead to the bio and action photos and the second (e.g. "Meet Afure!") will lead to those candid photos of players posing, acting goofy, hugging each other and so on.
My ad-blocker, OS and browser may be preventing me from seeing other stuff at this site beyond the drop-down menu and the links at the bottom, so if anyone notices other good stuff on this site, please advise.
