I think XF is just trying to make sure he's sure, as best he can, about his decision. And getting more of a feel for how he clicks with teammates and coaches in person is a great way to do it. With Iowa this week, he was with the team in the locker room before and after the game and during halftime. I'm guessing he did the same at ISU.
I know what you're saying about social media and fan reaction to how he's going about making his decision, but he shouldn't and likely doesn't give about that. He needs to gather as much information as possible to make the best decision for him, and go about it however he feels is best.
As I wrote, he can't control what the idiots and asses are going to do. It's a huge decision for him, not them.
