I realize that this is my first post ever, so it will be taken with an extra large grain of salt, and I completely understand that.
And I can't reveal my source, but this comes from someone with knowledge of the conversation -
During this most recent off-season, Lynn had been interviewing with other teams, looking to move up the offensive coaching ladder. Rex was aware of these interviews, and he called him in for a chat. He basically said, "Look, I'm not going to stop you from interviewing with other teams. But trust me, you want to stay here. This will be my last year, and the Pegulas love you. You're going to be the next Head Coach of the Buffalo Bills."
That wouldn't have made much sense at the time, but after the start to this season, and after Roman getting fired, it's starting to look a lot more likely. So why would Rex assume or even know this would be his last year? Did the Pegulas really give him that ultimatum that we heard about? Did Rex never plan to finish out his 5-year contract in the first place?
Maybe Rex will be fired during or after this season, maybe not. Maybe we'll get another big name coach to replace him, maybe not. But if Anthony Lynn is named the next Head Coach, whether it's interim or long-term, we'll know that Rex was ready for all of this months ago.
