If you don't know the story, Baylor football player Sam Ukwuachu was found guilty of assaulting a female soccer player at the university. Ukwuakchu was dismissed from Boise State for violence against his then girlfriend, and other behavioral issues. Baylor signed Ukwuachu, but now claim to not having known about any of this.
Simply put: buyer beware.
Whether Boise St Head Coach Chris Peterson made Baylor aware of the problem is immaterial. From a moral standpoint you would hope Boise St notified any and all teams interested in Ukwuachu, which I'd bet they did. Not doing so is reprehensible, but still, it's not their job to even have done so. They did their job by dismissing him. Certainly fire-able though, if the Boise St administration discovered they didn't pass on the information.
On the other hand, it's entirely Baylor's job to find out who they are inviting into their program and university. Clearly they did not do this. And because they didn't another student was physically and sexually assaulted.
Someone needs to be fired, and it's Art Briles.
