Is this a "T" on Coach?

[Ref Daddy]

Buried down in the "Why are we reluctant to call Ts?" thread is a comment I need advise on. Statement was about a ref that was "noticing" a coach's behavior partially for berating HIS OWN players.

Question: Is a technical valid for comments, aggression, chirping WITHIN and TOWARDS the same team?

How do you judge sportsmanship towards your own players or co-players?

Do we procter the relationship a coach has with his players?

Is a "T" valid this situation or only used with INTER - Team offenses!
