I watched the whole presser (it's up on the official site). The only time I recall him mentioning Shazier, was when he was talking about how they do these year end exit interviews, how it's a time for reflection, of gleaning things from the season that players can learn from. He mentioned that he thinks some players can learn from the experiences of other players, of things that they may not be aware of, of what type of struggles some of them have gone through. Here he points out that for instance Shazier may not be aware of the journey that Sean Spence went through. I'm presuming how Spence faced a dire future, maybe never being able to play again, and how far he's battled back from that devastating injury to continue his playing career. I reckon this is for a young player like Shazier to see how hard others have had to work to get to where they are.
My understanding of the context of this discussion is not along the lines of the original post in this thread, that this was meant to reference Shazier being a *****, or having to do with his bumps and bruises et al. I didn't hear or see anything that was a condemnation of Shazier.
