Freshman Jessie Rennie hit five 3-pointers and added 16 points, both career highs, for the Lady Vols (10-2), who open Southeastern Conference play on Thursday at home against Missouri.
Junior Rennia Davis also scored 16 points and sophomore Jordan Horston added 14 for Tennessee.
Jayla Thornton led the Bison (8-5), who had a four-game winning streak snapped, with nine points on 4-of-19 shooting, going 1-for-14 from 3-point range.
The Lady Vols were never threatened, scoring nine straight after a 2-2 tie and turning that into a 17-2 run. There were 12 straight points — and a 20-2 run — in the second quarter for a 44-14 halftime lead. Howard went 0-for-13 on 3s, shot 18% and hit just 2 of 10 attempts from the foul line.
The Bison shot 19% from the field for the game, made just one of 20 attempts behind the arc and 13 of 28 shots (46%) from the foul line.
Tipoff for the Lady Vols’ SEC opener Thursday at Thompson-Boling Arena was moved to 5 p.m. to avoid a direct conflict with the football team's appearance in the TaxSlayer Gator Bowl.
