It's definitely a nothing burger. But you also cannot deny that there is a certain image that exists, and like it or not, it's just not a smart move to draw that attention to yourself like Lebby did a few times. I don't see what life principle he was living by that made him bear that cross, but I think it was unnecessary. Do I care? Hell no, but I do think it's unnecessary.
Sort of like Leach with the noose tweet. Did he mean anything? No, but damn man, use a little bit of discretion. You're getting paid millions of dollars to coach football - there are a lot of eyes on you. Just stay in your lane unless it's something that truly violates a core value. Back to Briles - he's an old man, he can handle himself with Lebby out there taking up for him and printing shirts and having him on the sideline.
And no, you can't talk to him about this, or put shlt in his contract. You just have to hope it doesn't come up, and it's part of the deal when you decide to hire the guy.
