Impossible to tell if this photo posted by Popwrapped.com is Michael Sam or not. Even if it is Sam he was smart enough not to show his face and therefore he can deny it. But, it speaks to the bigger point that once you put yourself in the spotlight people who you thought you can trust or people you have done wrong in the past might turn on you.
My only advice to Sam is even if it isn’t him to be very careful about who he shares information, videos and photos with.
You can view the photo below it is NSFW.
