Bench Technical vs. Player Technical

[whistlesblow]

Surprised this has not been discussed yet, but what is the protocol for assessing a tech against an individual player on the bench vs. the more usual bench technical assessed against the bench collectively? Obviously the call in the Duke / Georgetown game is the genesis for this question. It had a significant impact on flow of the game and player availability and media reports are questioning whether it was a fan who actually made the offending remark. The video reply shows that the ref was not looking at the bench when the comment was made, but turned in response to something said and T'd up the individual player. It had a big impact on the game - 4th personal on major contributor, etc...

How does this work? I do not recall seeing a player T'd up on the bench, one who is not up, yelling, actively doing 'something', but I have only been paying close attention to officiating for a short time.

Any help on the guidelines for this would be appreciated. Thank you.
