I don't see other mangers criticizing their players in public. I have no idea what goes on behind the scenes but that is the place to do it.
Given the fact he virtually never shreds a player publically, I believe he has had some difficult discussions behind closed doors. The fact is this is a .500 team and probably should be worse and TL had coaxed as much out of this team as he possibly could. While I think Hazen is the right guy for the job he simply didn't give TL enough weapons to finish higher. I suspect TL will get a few more weapons next year.
