Now that the news is out there, I feel like I can say what my guy told me.
As the article indicates, all of these alleged situations occurred many years ago. It sounds like the Ravens have known for many years, but cannot confirm nor deny that. They got word early in the season that he was being investigated (hopefully the timing of his struggles make a lot more sense now) and used the PR weight to hold the story until after the season. The fun news is that his wife found out around the same time, and I'm sure you can put the pieces together there.
Privately, I've shared with a couple of you that Tucker and his wife do or did not live a traditional lifestyle. They've been spotted at notable swinger hangouts and it's apparently not exactly a hidden thing either. The cheating thing may or may not be related - I simply heard he was caught fucking around, but I don't know if that was in relation to the allegations (which shocker, would likely not be part of their arrangement) or something deeper with the swinger stuff.
Late in the season, they did apparently reconcile, so I would assume it had to do with the allegations, but this is me imparting my own thoughts based on what I know for full transparency.
