study guide question

[just another ref]

With time running out in the fourth quarter, team B scores giving them a three point lead. A-1 inbounds to A-2 near the sideline in front of team B's bench. A-2 releases a three point try prior to the horn sounding. Substitute B-6 enters the court and blocks the shot. Official charges B-6 with a technical foul for entering the court illegally and another technical foul for unsporting conduct. This ruling is correct.

I would say that this is true. The part about entering the court illegally is plain enough, and I have no trouble calling the shot block an unsporting act. Unless, of course there is some language in the book which would somehow string the two infractions together.

Awaiting the forum's meaningful insights.
