Exactly. Fox and Fangio, and Donatell for that matter has one of the strictest visions I have seen in terms of how he envisions a team. It's not just about a guy's talent. It's about the locker room, the football character, the person's make up, and how much they buy in, as well as can they execute what they want.
Seriously, you could chalk up Bennett and Marshall as guys who either were locker room trouble or didn't buy in. Forte - RB on the wrong side of 30. But Slauson, a guy who did everything they asked him to do, was the real shot heard round Halas Hall. He fit everything character-wise the team needed. But what they wanted was someone more proficient in run blocking in a zone scheme. To get down to that fine a detail and cut someone over it - this coaching staff doesn't **** around.
All the more reason why I would not be surprised if Jeffrey ends up playing out his tag and is allowed to walk at the end of the year, provided White ends up as all that.
