Key metric: Immigration Enforcement Effectiveness

Let me tell you something - this story is a GAME-CHANGER! Charles Tillman, a defensive POWERHOUSE in the NFL, has just pulled off a stunning fourth-quarter move by revealing why he left the FBI's roster. This isn't just a player trade, folks - it's a full-blown MORAL TOUCHDOWN! Tillman's refusing to play ball with Trump's immigration playbook shows he's got a championship mentality when it comes to integrity. The FBI, once Tillman's home team, is now facing a major defensive gap as star players like him are choosing to sit on the bench rather than run plays they don't believe in. This is the kind of locker room drama that can SHAKE UP an entire league! Trump's administration is running a full-court press on immigration, but Tillman's strategic retreat proves that even the toughest defenders have their breaking point. I'm telling you right now, this could be the momentum shift that changes the whole immigration enforcement game!
