The technical was issued in Summertown because the team took the floor and ran THROUGH the opposing team rather than around them. They normally (without incident) take the floor, half go up the sideline and half go along the wall and then meet at midcourt. But some of the players on the opposing team were leaning up against the wall/mat (stretching, etc..) so in effect, half of the Summertown team "technically" ran THROUGH the opposing team, resulting in the T.
According to the rule, this would result in a Technical. Some officials would look the other way, and some wouldn't. Just so happens, on this night, one of the officials that wouldn't look the other way was there.
