Concerns about Kansas’ three-point shooting may have been a bit premature after three games of the 2017-18 season. The Jayhawks, who hit 8 of 28 threes in a four-point victory over Kentucky on Nov. 14 and entered Tuesday’s game against Texas Southern at 39.8 percent from behind the arc, came out firing early and often — and with accuracy — in a record-setting 114-71 victory over the Tigers at Allen Fieldhouse. KU is 4-0. The 114 points were second-most scored in a game by the Jayhawks in the 15-year Bill Self era. Svi Mykhailiuk led the three-point parade with five threes in seven attempts.
