I’ve actually seen Kansas play twice in person already. Saw them play Vs Tennessee in Las Vegas in a fairly close game, saw them play most of the game yesterday. Their bench is very animated. One thing I noticed and did not like because I’m not sure I’ve seen it from any bench… when an opposing player is shooting a 3 in front of their bench, they literally stand up and scream in the players ear to distract them. I know it’s whatever it takes, but I didn’t like that.

I saw that yesterday also, found it very unsportsmanlike. Aren't there rules about bench behavior?

If the bench players are rising from their seat during play to disrupt the opponent, then that is a clear violation.
It would be nice to have a poster visible to the court "All players shall remain seated on the bench while the ball is live"

Misconduct by players, coaches, and bench personnel is not permitted� There is continued support for officials to enforce rules against misconduct by players, coaches, and bench personnel� Players' taunting, baiting, finger-pointing, trash-talking, and inappropriate gestures have increased during the past several seasons� Players and coaches are permitted to celebrate an individual or team accomplishment, but they cannot direct that celebration towards their opponent� Also, players and coaches are not allowed to disrespectfully or inappropriately address and/or gesture at an official after a ruling is made on the court� Player and coach behavior, which in the judgment of the official is determined to be a taunt of an opponent or a disrespectful act toward an official, shall be penalized by assessing a technical foul�
....
f� No opponent (player or bench personnel) shall disconcert (e�g�, taunt, bait, gesture or delay) the free-thrower�
....
Art. 4. Bench Technical Fouls
The head coach is responsible for the conduct and behavior of all bench personnel�
a� Committing misconduct, including, but not limited to, the following:
...
4� Taunting or baiting an opponent�
5� Objecting to an official’s decision by rising from the bench or using gestures�
6� Inciting undesirable crowd reactions�

d� All bench personnel shall remain seated on the bench while the ball is live, except as follows:
2� To spontaneously react to an outstanding play, immediately sitting down on the bench afterward�
....
b� Assistant coaches and other bench personnel. All bench personnel, with the exception of the head coach, are required to be seated on the bench while the ball is live except to react spontaneously to an outstanding play and then to immediately return to sitting on the bench� Violations by players, and especially assistant coaches, should not be tolerated by officials� When assistant coaches or bench personnel are violating bench decorum rules in a minor way, the official shall inform the head coach and request that they handle the situation� This is an official warning. Any further violation by bench personnel shall result in a technical foul assessed to the offender� Egregious (blatant) conduct violations by assistant coaches or bench personnel need no warning and shall immediately result in a technical foul� A technical foul assessed to bench personnel is also assessed as an indirect technical foul�
